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.

The speed of light in a transparent medium is 0.6 times that of its speed in vacuum. What is the refractive index of the medium?

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.

Consider a ray of light passing from one medium to another. If the angle of refraction is less than the angle of incidence, will the speed of light in the second medium be less or more than that in the first medium?
