Question:
The speed of light is maximum in:
The speed of light is maximum in:
Show Hint
The speed of light in a vacuum is approximately \(3 \times 10^8\) meters per second.

- Water
- Glass
- Diamond
- Vacuum
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The speed of light is maximum in a vacuum. This is because the speed of light is slower in materials such as glass, water, or diamond, which have refractive indices greater than 1. In a vacuum, the refractive index is 1, so light travels at its maximum speed.

- Name the type of lenses required by the persons for the correction of their defect of vision called presbyopia. Write the structure of the lenses commonly used for the correction of this defect giving reason for such designs.
- The distance of an object from the first focal point of a biconvex lens is \( X_1 \) and distance of the image from second focal point is \( X_2 \). The focal length of the lens is:
- 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,
