Question

What happens when the white light goes through a glass prism?
A. A light dispersion and the formation of a 7 colors spectrum.
B. A light dispersion and the formation of a 6 colors spectrum.
C. A light reflection and the formation of a 6 colors spectrum.
D. A light reflection and the formation of a 7 colors spectrum.

Answer 1

Hint: A prism is a 3-dimensional shape with two identical shapes facing one another . These identical shapes are called “bases”. The bases are often a triangle, square, rectangle or the other polygon. The rest faces of the prism are parallelograms or rectangles.

Complete step by step solution:
Upon passage through the prism, the white light is separated into its component colors - red, orange, yellow, green, blue, indigo and violet.
Upon passage through the prism, the white light is separated into its component colors - red, orange, yellow, green, blue and violet. The separation of light into its different colors is understood as dispersion.
It was mentioned within the Light and Color unit that every color is characteristic of a definite wave frequency; and different frequencies of sunshine waves will bend varying amounts upon passage through a prism.
During this unit, we'll investigate the dispersion of sunshine in additional detail, pondering the explanations why different frequencies of sunshine bend or refract different amounts when passing through the prism.
Hence, the right option is (A).

Note: A rainbow has seven colors because water droplets within the atmosphere break sunlight into seven colors. A prism similarly divides light into seven colors. When light leaves one medium and enters another, the sunshine changes its propagation direction and bends. This is often called refraction.
