Mark the correct light ray as it travels through different mediums.

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.

Light travels with different speeds in different mediums.

The critical angle between a certain transparent medium and air is phi . A ray of light travelling through air enters the medium at an angle of incidence equal to its Brewster angle theta. Therefore, the angle of refraction is

The critical angle between a certain transparent medium and air is phi . A ray of light travelling through air enters the medium at an angle of incidence equal to its Brewster angle theta. Therefore, the angle of refraction is

Ray of light bends as light travels from one medium to another.

Figure shows a ray of light as it travels from medium A to medium B. Refractive index of the medium B relative to medium A is

Sound travels with different speeds in different mediums.

Consider the following statement A and B and identify the correct answer A) Primary waves travels in a medium with speed of light in all directions. B) Secondary waves travels in backward direction only but not with speed of light

Statement I: Lights of different colors travel with different speeds in vacuum. Statement II: Speed of light depends on medium.

A ray of light is incident as a normal ray on the surface of separation of two different mediums. What is the value of the angle of incidence in this case ?
