Question

Which of the following colors has the shortest wavelength?

1) Yellow
2) Orange
3) Red
4) Green

Answer 1

Option 4: Green has the shortest wavelength compared to yellow, orange, and red in the visible light spectrum, following the ROY G BIV mnemonic for color order from longest to shortest wavelength.

Step-by-step explanation:

Of the following colors: yellow, orange, red, and green, the color with the shortest wavelength is green. In the visible light spectrum, colors are perceived based on their wavelengths. This range can be remembered using the mnemonic ROY G BIV, which stands for Red, Orange, Yellow, Green, Blue, Indigo, and Violet, indicating the order of colors from the longest to the shortest wavelength. Therefore, compared to yellow, orange, and red, green light has a shorter wavelength.

In the visible light spectrum, the color with the shortest wavelength is violet. The colors of visible light can be remembered using the mnemonic ROY G BIV - Red, Orange, Yellow, Green, Blue, Indigo, and Violet. Violet has the shortest wavelength, while red has the longest wavelength. Therefore, out of the given options, none of them have a shorter wavelength than violet.

Answer 2

Blue, because the more cold the colour is that shorter wavelength it has.

Blue has a wavelength of 380-450 nm compared to other colours like red or orange which has a wavelength larger. Red being 620-750 nm and orange being 590-620 which is a lot bigger than blue

Hope this helps, good luck! You’re doing well!
