What is the law of reflection?
The angle of incidence equals the angle of reflection
200
If light travels into a medium with a higher index of refraction, what happens to the light?
It bends towards the normal

What are the characteristics we use to describe an image
upright/inverted, larger/smaller, real/virtual
300
What is the Magnification Equation?
M = hi/ho = -di/do
300
What is diffraction?
waves bending around an obstacle/through an opening
300
What is refraction?
Light bending because of a new medium

If the object is beyond the focal length, what are the 3 characteristics of the image?
smaller, inverted, real
400
What is the mirror equation?
1/f = 1/di + 1/do
400
What are the 2 types of interference?
constructive and destructive
400
What is reflection?
waves/particles bouncing off a surface

Draw the ray diagram of an object placed at the focal length of a concave mirror.
No image because reflected rays are parallel
500
If the object distance is infinitely far away, then the image distance is equal to.. ...Why?
the focal length, because the object value would be zero so, 1/f=1/di

How is echoing down a hall different than someone singing off pitch?
echoing down a hall is reflection of sound, off-pitch results from wave interference
500
How is refraction different from diffraction?
Refraction bends because of a new medium, Diffraction occurs because of an obstacle
