Arrange these in ascending order of wavelength while propagating through different medium.
(A) Light propagating in air
(B) Light propagating in water
(C) Light propagating in diamond
(D) Light propagating in glass
Choose the correct answer from the options given below :
- A (A) \(<\) (B) \(<\) (D) \(<\) (C)
- B \(( A )=( B )=( C )=( D )\)
- C (C) \(=\) (D) \(<\) (B) \(<\) (A)
- D \(( C )<( D )<( B )<( A )\)
Answer & Solution
Correct Answer
(D) \(( C )<( D )<( B )<( A )\)
Step-by-step Solution
Detailed explanation
\( \lambda_m = \frac{\lambda_0}{n} \) \( n_{diamond} > n_{glass} > n_{water} > n_{air} \) \( \lambda_C < \lambda_D < \lambda_B < \lambda_A \)
