Waves change direction as they enter or leave a lens due to refraction, which is the bending of light as it passes through a medium with a different optical density. This bending occurs because light waves travel at different speeds in different mediums, causing them to change direction at the interface.

What happens to light waves as they enter and leave a prism?
Light waves undergo refraction as they enter and leave a prism. When entering a prism, they bend towards the base of the prism due to the change in speed. When leaving the prism, they bend away from the base due to the speed change again.
What causes light waves to bend when they enter a new medium at angle?
Light waves bend when they enter a new medium at an angle due to a change in speed caused by the change in the medium's refractive index. This change in speed results in a change in the direction of the light wave, a phenomenon known as refraction.
What happens to the direction of electromagnetic waves in media?
The direction of electromagnetic waves can change when they enter a different medium due to effects like refraction, reflection, or absorption. These changes in direction depend on the properties of the new medium, such as its refractive index, leading to phenomena like bending, bouncing, or attenuation of the waves.
How do light waves travel as they enter the water?
As light waves enter water, they slow down due to the change in the medium's density. This change in speed causes the light waves to refract or change direction, bending towards the normal line. The extent of bending depends on the angle of incidence and the difference in the refractive indices of air and water.
When light waves slow down do they change direction?
When light waves slow down as they travel from one medium to another, such as from air to glass, they do change direction. This change in direction is called refraction and occurs due to the change in speed of the light waves in the new medium.

When light waves slow down as they travel from one medium to another, such as from air to glass, they do change direction. This change in direction is called refraction and occurs due to the change in speed of the light waves in the new medium.
What direction do waves changes?
Waves change direction when they encounter a change in medium or boundary that causes them to refract or reflect. Refraction occurs when waves change speed as they move from one medium to another, causing them to bend. Reflection occurs when waves bounce off a boundary, changing direction.
Electromagnetic waves slow down or change direction?
Electromagnetic waves do not slow down in a vacuum. However, they can change direction when they encounter different mediums, such as transitioning from air to glass. This change in direction is known as refraction.
What is the passage of an EM wave through a medium?
when EM waves encounter a material medium, they can interact with it in much the same way that mechanical waves do. A mechanical wave transfer energy in two ways. As it travels, the wave moves potential energy from one place to another.
How does a change in speed cause a change in direction?

Why do seismic waves change speed?
"True, the Seismic Waves change speed and direction when they encounter different materials."
What happens when there is reflection in light waves?
That means that the light waves rebound, and change direction.
What refers to the bending of light waves when they pass through another substance?
Refraction is the bending of light waves when they pass through another substance. This phenomenon occurs due to a change in the speed of light as it travels from one medium to another, causing the light waves to change direction.
