100

These words are used to describe light travelling in straight lines.

Rectilinear Propagation 

100

This is equal to exactly half the radius of curvature of a lens.

What is Focal length?

100

All sound waves are of this variety, due to the movement of their particles.

What is a longitudinal wave?

100

This measurement is taken from the equilibrium point of a wave to its maximum height

What is amplitude?

100

This is the speed of light.

What is 3x10^8 meters/second?

200

Refraction

What is when waves involve a change in the direction of propagation as they pass from one medium to another

200

If you know the focal length of a concave mirror, where should you place an object so that its image is upright and larger compared to the object?

What is f>do>0 (inside the focal length will produce an image that is upright, larger, and virtual)

200
This is directly related to the intensity of a sound wave.
What is amplitude?
200

The period of a wave is 0.1 seconds. Determine the frequency  of the wave.

f=1/T = 1/0.1s = 10Hz 

200
This high energy Electromagnetic radiation is used in medical imaging.

What is x-rays?

300

Law of Reflection

What is waves will always reflect in such a way that the angle at which they approach the barrier equals the angle at which they reflect off the barrier

300

This fuzzy part of a shadow is caused by light emitted from a non-point source.

What is penumbra?

300
This is directly related to the frequency of a wave and subsequently affects the sound that you perceive.
What is pitch?
300

What is the speed of a periodic wave disturbance that has a frequency of 3.50Hz and a wavelength of 0.700m?

What is 2.45m/s; v=lambda(f) = 0.700mx3.5Hz = 2.45m/s 

300
Electromagnetic spectrum
What is continuous range of frequencies
400
Transverse wave
What is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves
400

Describe the image of an object reflecting off a convex mirror. (Image type, size, orientation)

virtual, smaller, upright

400

Musicians do this to change the resonant frequency of their instrument to play different notes?

What is change the length?

400

A crest 3cm high approaches a trough 2cm deep. What is the height of the superimposed wave while they pass through each other?

What is 1 cm?

400
This property of waves directly affects the way a visible (or non-visible) wave is perceived (or not perceived, still depending on the same characteristic)
What is wavelength?
500
Longitudinal wave
What is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves.
500

This type of mirror causes the objects seen in your passenger side mirror to be closer than they appear.

What is convex?

500

A hiker shouts towards a vertical cliff 465m away. The echo is heard 2.75s later. a) what is the speed of sound of the hiker's voice in air?

What is 338m/s v=d/t = 2(465m)/2.75s = 338m/s

500
An incident ray in air (n=1.0) is approaching the boundary with an unknown material at an angle of incidence of 59.1°. The angle of refraction is 44.2°. Determine the index of refraction of the unknown material.
What is nr=1.23 (ni)sin(theta i) = (nr)sin(theta r)
500

This type of wave comes from your cell phone and is the least dangerous.

What is radio waves?
