concept two

Question 1

real world example of reflection

Answer 1

echo

Question 2

real world example of refraction

Answer 2

pencil looking bent in a glass of water

Question 3

real world example of diffraction

Answer 3

looking at a street lamp through a crack in a curtain

Question 4

real world example of absorption

Answer 4

A dark shirt feels warmer in the sun than
a light colored shirt

Question 5

real world example of interference

Answer 5

Noise-canceling headphones

Question 6

real world example of resonance

Answer 6

Tuning forks or stringed instruments

Question 7

law of refection

Answer 7

Angle of incidence = Angle of reflection

Question 8

incidence ray

Answer 8

is the wave that sticks the surface

Question 9

reflected ray

Answer 9

wave that bounces off the surface

Question 10

how does a prism work

Answer 10

Light waves enter a prism and slow down, due
to change in medium

This causes waves to bend (refract)

Different colors of light are different wavelengths,
therefore travel at different speeds

This causes them to bend different amounts and
the colors separate out ROYGBIV

Question 11

two factors that effect the amount of diffraction

Answer 11

The size of the object the waves hit
and The wavelength of the waves

Question 12

constructive interference

Answer 12

two or more waves add together
-like parts of the wave must match
-results in an increase of amplitude on the wave

Question 13

destructive interference

Answer 13

when two or more waves subtract from one another when they overlap.
