Explanation of Solution
Introduction:
When light passes through the different materials/media its speed decreases (except in vacuum). The change in speed depends on the refractive index of that particular material/media.
For a given frequency the wavelength is directly proportional to the speed of light. Mathematically,
Wave speed = frequency wavelength.
When a light wave travels from one medium to another the speed slows down and that does not affect the frequency of light since the wavelength is shorter.
Conclusion:
When a wave travels from one medium to other medium, the frequency never changes.

Explanation of Solution
Introduction:
When a light passes through the different materials/media its speed actually decreases (except in vacuum). The change in speed depends on the refractive index of that particular material/media.
The speed of light is directly proportional to the wavelength of the light that travels from one medium to another medium.
Mathematically,
Wave speed = frequency wave speed.
When a light wave travels from one medium to another the speed slows down and the wavelength is decreased as it is directly proportional to speed of light.
Conclusion:
When a light wave travels from one medium to another the wavelength is decreased as it is directly proportional to the speed of light.

- 4 Problem 4) A particle is being pushed up a smooth slot by a rod. At the instant when 0 = rad, the angular speed of the arm is ė = 1 rad/sec, and the angular acceleration is = 2 rad/sec². What is the net force acting on the 1 kg particle at this instant? Express your answer as a vector in cylindrical coordinates. Hint: You can express the radial coordinate as a function of the angle by observing a right triangle.
