Part C: When light passes through a denser medium, how does the wavelength affect the angle of refraction?

When light passes from a less dense medium to a denser medium, it slows down and bends towards the normal line. This is known as refraction. The angle of refraction depends on the wavelength of the light.

Step 1: Understand the concept of refraction Refraction is the bending of light as it passes from one medium to another. This happens because light travels at different speeds in different mediums.

Step 2: Understand the relationship between wavelength and speed of light The speed of light in a medium is inversely proportional to the wavelength. This means that light with a longer wavelength will travel slower than light with a shorter wavelength.

Step 3: Understand the relationship between speed of light and angle of refraction The slower the light travels in a medium, the more it bends towards the normal line. This means that the angle of refraction is larger for light with a longer wavelength.

Step 4: Conclusion When light passes through a denser medium, the wavelength of the light affects the angle of refraction. Light with a longer wavelength will have a larger angle of refraction because it travels slower in the denser medium.
