Question:
The frequency of a light ray is \( 6 \times 10^{14} \) Hz. Its frequency when it propagates in a medium of refractive index 1.5, will be:
The frequency of a light ray is \( 6 \times 10^{14} \) Hz. Its frequency when it propagates in a medium of refractive index 1.5, will be:
Show Hint
Remember that the frequency of light does not change when it passes through a different medium, only the wavelength changes.

- \( 1.67 \times 10^{14} \) Hz
- \( 9.10 \times 10^{14} \) Hz
- \( 6 \times 10^{14} \) Hz
- \( 4 \times 10^{14} \) Hz
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The frequency of light remains constant when it passes from one medium to another, only the wavelength changes. Therefore, the frequency in the new medium will remain \( 6 \times 10^{14} \) Hz.
Thus, the correct answer is option (3).

- A beam of light coming from a distant source is refracted by a spherical glass ball (refractive index 1.5) of radius 15 cm. Draw the ray diagram and obtain the position of the final image formed.
- The speed of light in two media '1' and '2' are \( v_1 \) and \( v_2 \) (\( v_2>v_1 \)) respectively. For a ray of light to undergo total internal reflection at the interface of these two media, it must be incident from:
- In a Young's double-slit experiment, two light waves, each of intensity \( I_0 \), interfere at a point, having a path difference \( \frac{\lambda}{2} \) on the screen. Find the intensity at this point.
- A spherical convex surface of radius of curvature \( R \) separates glass (refractive index \( 1.5 \)) from air. Light from a point source placed in air at a distance \( \frac{R}{2} \) from the surface falls on it. Find the position and nature of the image formed.
- A thin lens is a transparent optical medium bounded by two surfaces, at least one of which should be spherical. Applying the formula for image formation by a single spherical surface successively at the two surfaces of a lens, one can obtain the 'lens maker formula' and then the 'lens formula'. A lens has two foci - called 'first focal point' and 'second focal point' of the lens, one on each side.
