The colour of white light which is deviated maximum on passing through the glass prism is:
Show Hint
Remember the VIBGYOR order when white light disperses:
- Violet deviates the most,
- Red deviates the least.

The Correct Option is B
Solution and Explanation
Step 1: Understand dispersion of light through a prism.
When white light passes through a glass prism, it splits into its constituent colors due to different degrees of refraction. This phenomenon is called
dispersion.
Step 2: Know the order of deviation. The extent of deviation depends on the wavelength: -
Violet has the
shortest wavelength and is deviated the most. -
Red has the
longest wavelength and is deviated the least.
Step 3: Conclude based on deviation. Hence,
violet light is deviated the most when white light passes through a prism.

- At the interface between two materials having refractive indices \( n_1 \) and \( n_2 \), the critical angle for reflection of an EM wave is \( \theta_c \). The \( n_1 \) material is replaced by another material having refractive index \( n_3 \), such that the critical angle at the interface between \( n_1 \) and \( n_3 \) materials is \( \theta_{c3} \). If \( n_1 > n_2 > n_3 \), \( \frac{n_2}{n_3} = \frac{2}{5} \), and \( \sin \theta_{c2} - \sin \theta_{c1} = \frac{1}{2} \), then \( \theta_{c1} \) is:
