Question

Light of three colours A, B and C of wavelengths A₁, A2 and A3 is passed through a plane boundary. If A bends more than B and B bends more than C, then correct relation between A₁, A₂ and A3 is. A. A₁ > A₂ > A3

B. A1 A2 A3

C. A₁ <1₂>13.

D. A₁ = A₂ = A3​

Answer 1

Answer:

When light of two colours A and B are passed through a plane boundary, A is bent more than

Answer 2

OPTION (B) IS CORRECT.

(B) $A_{1}$ < $A_{2}$ < $A_{3}$

Explanation:

• When a light undergoes refraction it bends from its original path.
• The white light disperse into 7 colours, that are red, orange, yellow, green, blue, indigo, and violet. The red light bends the least and the violet light bends the most.
• The shorter wavelength of light will bend more than the longer wavelength of light.
• As A bends more than B, its wavelength will be less than B. And B bends more than C so its wavelength will be less than C.
• Therefore, option (B) is correct.
