The speed of light depends

Assertion : Wavefronts obtained from light emitted by a point source in an isotropic medium are always spherical. Reason : Speed of light in isotropic medium is constant.

A: Speed of light in a medium is independent of the motion of the source relative to the medium. R: Speed of light in a medium depends on the motion of the observer relative to the medium.

A: The speed of light in water is not same as that in flowing water. R: The speed of light in water is not independent of the relative motion between the observer and the medium.

n=(v)/(c) where n denotes the refractive index of a medium, v the speed of light in the medium and c the speed of light in vacuum.

A: When a narrow pulse of light is sent through a medium, it doesn't retain its shape as it travels through the medium. R: Since the speed of propagation in a medium depends on wavelength , different wavelength components of the pulse travel with different speeds.
