Light is an example of something that travels in waves. Light waves come in many different varieties, and can be seen as many different colors. What is the main difference between a light wave that produces the color blue and a light wave that produces the color red? A. Magnitude B. Wavelength C. Direction D. Amplitude

option (B)

Explanation:

Light waves are electromagnetic waves which can be seen by our eye.

The white light contains seven colours of light which are given below:

Violet

Indigo

Blue

Green

Yellow

Orange

Red

This is the order of increasing wavelength and the decreasing frequency.

So, the wavelength of blue light and the red light is different.

Option (B)

Explanation:

Light is a form of electro-magnetic waves. This light wave has distinct range of wavelength that allows it to form different colors of light. This means that the color of the light produces depending on the amount of wavelength it comprises.

The visible light ranges from Violet to Red, and this is observed as different colors when each of these electromagnetic waves strikes our eyes at a certain angle. The violet light has the shortest wavelength of about 410 nm, where the red light has the highest wavelength of about 650 nm.

Thus, the correct answer is option (B).
