What Color Light Has The Longest Wavelength


What Color Light Has The Longest Wavelength?

red light

Which of these colors has the longest wavelength?


Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together they make white light.

Which color has the longest wavelength and lower frequency?


We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength.

Which light has longest wavelength red or blue?

Blue light has shorter waves with wavelengths between about 450 and 495 nanometers. Red light has longer waves with wavelengths around 620 to 750 nm. Blue light has a higher frequency and carries more energy than red light.

Which color of light has the longest wavelength which color has the greatest frequency and energy?


Violet waves have the highest frequencies. Red waves have the longest wavelengths.

Which has the longest wavelength?

Radio waves
Radio waves have the longest wavelength and gamma rays have the shortest wavelength.

What color has the second longest wavelength?

The visible colors from shortest to longest wavelength are: violet blue green yellow orange and red. Ultraviolet radiation has a shorter wavelength than the visible violet light. Infrared radiation has a longer wavelength than visible red light. The white light is a mixture of the colors of the visible spectrum.

Why does the color red have the longest wavelength?


As the full spectrum of visible light travels through a prism the wavelengths separate into the colors of the rainbow because each color is a different wavelength. Violet has the shortest wavelength at around 380 nanometers and red has the longest wavelength at around 700 nanometers.

Which Colour has maximum wavelength in vibgyor?

Red light has longer wavelengths than the blue light. The angle of deviation by a prism is not the same for all the wavelength (colours) of light. Hence the prism disperses white light into its constituent colours. The red is deviated least and the violet most.

Which color scatter the most?

Blue colour light

Blue colour light gets scattered most in all directions while after entering the atmosphere of the earth because of the shortest wavelength. Therefore (C) Blue is the correct answer. The appearance of the blue colour of the sky is due to this scattering of the blue colour of the spectrum of the sunlight.

Which has a longer wavelength red or green light?

Light has a wavelength of about 380 nm to 750 nm depending on color. nm means nanometer one billionth of a meter.

Color Wavelength Range (nm)
Red 620–750
Orange 590–620
Yellow 570–590
Green 495–570

Which Colour of the spectrum has a longest wavelength and B shortest wavelength?

Red has longest wavelength. Violet has shortest wavelength.

How do you find the longest wavelength?

Which color of visible light has a longer wavelength than yellow light?

1. Yellow light has a longer wavelength than green light.

What is the longest to shortest wavelength?

Order is as follows (shortest to longest wavelength): Gamma X-Rays UV Visible Infrared Microwaves Radio Waves.

Does green or blue light have a longer wavelength?

Green light has a longer wavelength than blue light.

Which has longer wavelength blue or Indigo?

Explanation: Indigo wavelength is between 420 and 450 nm. Blue wavelength is between 450 and 495 nm.

Does white light has a wavelength?

Wavelength of White Light

See also 1 meter how many kilometers

Depending on the wavelength one can see the visible light colour. … Hence white cannot be assigned to a single wavelength as it is composed of wavelengths of different colors. So the white light has the wavelength between the ranges of 400 – 700 mm.

Why white light is the strongest light?

A true white light will have equal intensity in the low-end and the high-end of the spectrum therefore more intensity on the high-end part than a yellowish light and will be more energetic.

Why does red light have a longer wavelength than blue?

Red light has a wavelength close to 700nm and blue is close to 400nm. Wavelength is related to frequency by the equation c (speed of light) = wavelength * frequency. So red has lower frequency and lower energy than blue light.

Does Indigo have a wavelength?

Optical scientists Hardy and Perrin list indigo as between 445 and 464 nm wavelength which occupies a spectrum segment from roughly the color wheel (RGB) blue extending to the long-wave side towards azure.

Which has largest wavelength vibgyor?

  • Red has the longest wavelength among the given options.
  • From VIBGYOR – R (red) has the longest and V(violet) has the shortest.
  • It is reverse for frequency.

Can a red apple reflect light?

In white light a red apple absorbs all the colors (including green) of the spectrum except red which it reflects. … Since there is no red light shining on the apple there is no red light to reflect so the apple appears black.

Which light scatters the most?

Air molecules scatter light in this way because they are very small (much smaller than the wavelength of visible light). Violet has the shortest wavelength and is scattered the most.

Which Colour is least deviated?

Yellow is the colour of white light that is the least deviated by a prism because it has the largest wavelength of the colours given in the alternatives.

Which Colour of light scatters the least and which Colour the most?

red light

The higher the scattering the shorter the wavelength of light this is why blue or violet light scatters the most and red light scatters the least.

Does purple have a wavelength?

Scientifically purple is not a color because there is no beam of pure light that looks purple. There is no light wavelength that corresponds to purple.

Does Yellow have the shortest wavelength?

1 Angstrom = 1010 meters. The order of colors in light arranged from shortest wavelength to longest is called the visible spectrum of light.

Approximate wavelength For the various colors.
Color Wavelength (nm)
Yellow 597 – 577
Green 577 – 492
Blue 492 – 455
Violet 455 – 390

What wavelength is pink light?

Pink isn’t out there. True no single wavelength of light appears pink. Pink requires a mixture of red and purple light—colors from opposite ends of the visible spectrum.

Which Colour has the longest wavelength Mcq?


Answer: (1)

Red – Longest wavelength of the colour.

Which color has the lowest and the highest energy?

When it comes to visible light the highest frequency color which is violet also has the most energy. The lowest frequency of visible light which is red has the least energy.

Which color has the shortest wavelength of light Mcq?

The visible wavelengths cover a range from approximately 0.4 to 0.7 µm. The longest visible wavelength is red and the shortest is violet.

What is the longest wavelength light that will eject an electron?

520 nm

The longest-wavelength light that causes an electron to be emitted from gaseous lithium atom is 520 nm.

How do you find the maximum wavelength of light?

See formula wavelength = speed of wave / frequency. How do I work out the maximum wavelength? To determine the maximum wavelength of light you simply use the energy equation. If you know the amount of energy required for the reaction you plug it into the equation λ = hc/E.
