Question

In a vacuum, the speed of light depends upon

• A. wavelength
• B. frequency
• C. intensity of light
• D. none of these

Answer 1

The correct option is D

none of these

1. In a vacuum, all colors of the visible spectrum travel at the same velocity
2. This velocity is numerically equal to $3x{10}^8$ ms^-1.
3. All the components of light travel together irrespective of their wavelengths and frequencies.

Thus, the correct option is (D).
