Interference when a crest overlaps a crest.
What is constructive interference?
What happens to the speed and frequency of a wave when it enters a more dense medium
Speed decreases. Frequency remains the same.
If n of a new medium is smaller than n for the original medium, a wave will bend_____________ from the normal line.
What is away?
The speed of light in corn oil
2.04 x 10^8 m/s
An ambulance blaring its siren is traveling towards you. What is happening to the frequency and wavelength of the siren sound as the ambulance approaches you.
The wavelength is getting smaller and the frequency is getting bigger. High frequency means you hear a higher pitch.
The period of a wave that has a frequency of 60. hertz? What does this mean?
0.017 seconds.
The time it takes for the wave to complete one full cycle.
Two waves traveling in the same medium and having the same wavelength (3m) interfere to create a standing wave. What is the distance between two consecutive nodes on this standing wave?
1.5 m
What is the angle of reflection for this light ray?
25 degrees
The diagram shows a transverse water wave moving to the right. At the instant shown, a cork at point P on the water's surface is moving in this direction.

What is the minimum wavelength of orange light?
596 nm
(5.96 x 10^-7 m)
You shine blue light (frequency of 6.3 x 10^14 Hz) through two slits which are separated by 1mm. The distance between the slits and the a wall which the light hits is 2m. How far is the first bright band above the central bright band?
2 mm
If a light ray is traveling from water into diamond at an angle of incidence of 20 degrees, what will be the angle of refraction?
What is 10.8 degrees?
