Question:
The cause of twinkling of stars is:
The cause of twinkling of stars is:
Show Hint
Atmospheric refraction causes the apparent position of stars to shift, leading to the twinkling effect observed from Earth.
Updated On: Nov 5, 2025
- Scattering of light
- Reflection of light
- Atmospheric refraction
- None of these
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The twinkling of stars is caused by atmospheric refraction. Light from a star travels through different layers of the Earth's atmosphere, which have varying optical densities. As a result, the light undergoes continuous bending, making the star's position appear to shift slightly. This fluctuation in brightness creates the twinkling effect.

- In a Young's double slit experiment, two slits are located 1.5 m apart. The distance of screen from slits is 2 m and the wavelength of the source is 400 nm. If the 20 maxima of the double slit pattern are contained within the centre maximum of the single slit diffraction pattern, then the width of each slit is $ x \times 10^{-3} \, \text{cm} $, where x-value is:
- Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R)
Assertion (A) : Refractive index of glass is higher than that of air.
Reason (R) : Optical density of a medium is directly proportionate to its mass density which results in a proportionate refractive index.
In the light of the above statements, choose the most appropriate answer from the options given below : - In a Young's double slit experiment, the source is white light. One of the slits is covered by red filter and another by green filter. In this case,
