What is Reflection in wave behavior?

Back

Reflection is the bouncing back of a wave when it hits a surface that does not absorb the wave's energy. Example: Seeing your image in a mirror.

Front

What is Refraction in wave behavior?

Back

Refraction is the bending of a wave as it passes from one medium to another, changing its speed. Example: A pencil appearing bent in a glass of water.

Front

What is Diffraction in wave behavior?

Back

Diffraction is the spreading out of waves when they pass through a narrow opening or around obstacles. Example: Light spreading as it passes through a window.

Front

What is Absorption in wave behavior?

Back

Absorption is the process by which a wave's energy is taken in by a material, converting it to other forms of energy. Example: A black surface absorbing light.

How does Reflection help in seeing images?

Back

Reflection allows light waves to bounce off surfaces, enabling us to see images, such as our reflection in a countertop.

Front

What is the Law of Reflection?

Back

The Law of Reflection states that the angle of incidence is equal to the angle of reflection when a wave reflects off a surface.

Front

What is the angle of incidence?

Back

The angle of incidence is the angle between the incoming wave and the normal (a line perpendicular to the surface) at the point of incidence.

Front

What is the angle of reflection?

Back

The angle of reflection is the angle between the reflected wave and the normal at the point of reflection.

Front

What is an example of Refraction in everyday life?

Back

An example of refraction is when a straw appears bent when placed in a glass of water.

What is an example of Diffraction in sound?

Back

An example of diffraction in sound is hearing someone speaking around a corner.
