Reflection and Waves Honors

Front

Reflection

Back

When a wave strikes an object and bounces off of it.

Front

What type of wave is an Echo?

Back

Echoes are reflected sound waves. Sound waves are longitudinal or compressional waves.

Front

Law of Reflection

Back

The angle of incidence is always equal to the angle of reflection.

Front

Refraction

Back

The bending of waves caused by a change in speed as it moves from one medium through another. The greater the change in speed, the more the wave bends.

Front

Diffraction

Back

When an object causes a wave to change direction and bend around it.

Front

Factors affecting diffraction

Back

The amount of diffraction depends on the size of the object the waves hit and the wavelength of the waves.

Front

Sound waves vs. light waves in diffraction

Back

Sound waves tend to diffract much better than light waves because they are much larger.

Front

Absorption

Back

Energy from the wave gets converted to thermal energy.

Front

What color of clothing are better at absorbing light and why.

Back

Dark colors are better at absorbing light waves than light colors, making them better to wear in winter to stay warmer outside. You stay warmer because light waves are converted to thermal energy.

Front

Interference

Back

When two or more waves combine to form a new wave.
