(Fill in the Blank)
What color of light has the longest wavelength?
Red
What is the trough of a wave?
The LOWEST part of a transverse wave.
the bending of waves, especially sound and light waves, around obstacles in their path.
What is DIFFRACTION
The speed of light is 300,000,000 km/sec.
What is false Correct Answer is: 300,000 km/sec.
_____ rays have the highest frequency.
What is GAMMA
_______ waves cannot be seen, are felt as heat, and have a lower frequency than visible red light.
What is INFRARED.
What is the crest of a wave?
The HIGHEST part of a transverse wave.
the process in which two or more light, sound, or electromagnetic waves of the same frequency combine to reinforce or cancel each other, the amplitude of the resulting wave being equal to the sum of the amplitudes of the combining waves.
What is INTERFERENCE.
Electromagnetic waves can travel through a vacuum.

sound rays are not included in the ______________ spectrum.
What is ELECTROMAGNETIC
______ waves are visible.
What is VIOLET.
What is amplitude?
The maximum that particles of a medium move away from their rest position as a wave passes through the medium. (height of a wave)
A change in direction of one or more waves.
What is REFRACTION.
Density and matter affect the speed of waves traveling through it.

What is RADIO
What is wavelength?
The length between two waves.
Wave interaction is the interaction that is between surface gravity waves.
