What is a term that describes crests and troughs of light waves moving in phase?
Light waves with the same phase and frequency are said to be coherent.
What type of interference occurs when two waves are in phase?
Constructive
What are coherent waves?
COHERENT WAVESWhen the light waves are emitted from a single source and they have the zero phase difference between them then the waves are said to be coherent. The coherent waves are shown below:
If two light waves start out in phase with one another but one travels two wavelengths farther than the other before they come together will the waves be in phase or out of phase when they combine?
in phase
Light waves of one wavelength that travels with its crests and troughs aligned is called what?
Light waves of a single wavelength is known as being coherent. This allows constructive interference which occurs when two or more waves are in phase i.e. their crests and troughs are aligned.
When two identical waves arrive at the same place in phase there is?
... constructive interference.

What is incoherent light?
light waves that are out of phase with one another
What type of interference occurs when two waves are in phase?
Constructive
What property of light is defined by the distance between identical points on adjacent waves?
The property of light defined by the distance between identical points on adjacent waves is called wavelength. Wavelength is typically measured from peak to peak or trough to trough of a wave. It determines the color of light and is inversely related to the frequency of the wave.

How are radio waves and light waves similar?
Except for their wavelength (frequency) and energy per quantum, they're identical.
Is visible light faster than radio waves in a vacuum?
No. Their speeds are identical.
Can waves with different wavelength be coherent?
No. In order to be coherent, the light waves have to be in phase and stay in phase, and the only way for that to happen is for them to have the same wavelength and frequency.
Do radio waves travel at the speed of sound at the speed of light or at some speed in between?
'Radio' waves are physically and electrically identical to light waves except for their frequency (wavelength), and they travel at the same speed as light does.
