Question #4
What is when light hits an object (angle of incidence) it bounces back off the object at the same angle in which it hits (angle of reflection)?
100
Question #12 c only
What is the sound waves speeds up because sound travels quicker in liquids than in gases?
100
Question #16 Fil in the chart
What is (look on the board for answer)

Question # 16 a only
What is frequency.
200
Question # 6 a only

200
Question #9 b only

200
Question #23
Equation: Weight x height
What is 30000J
200
Question #6 b only
What is the energy in the wave moves horizontally and the wave also moves horizontally.
300
Question # 7 b
What is electromagnetic, empty space, gas, liquid, and solid?
300
Question #13 a only
What is (look at the board for an example)
300
Question #15 a only
What is the frequency of the sound waves are higher so the pitch of the sound is also higher?
300
Question #17.
What is A and C would have the highest potential energy because they are the furthest away from the ground, B would have the most kinetic energy because the pendelum would be moving the quickest at this point.
300
Question #19
What is all the colors of visible light are being absorbed by the object when it appears black, and all the colors of visible light are being reflected when an object appears white.
400
Question # 3

What is 812.5 J
400
Question #20
What is Radio, Microwave, Infared, Visible Light, UV, X-ray, Gamma rays.

Question #15 the first wave only.
What is 1. wavelength, 2. amplitude, 3. crest, 4. trough
500
Question #21
What is Red Orange Yellow Green Blue Indigo Violet
500
Question #15 b only
What is the frequency of the waves is lower therefore the sound's pitch is also lower?
500
The difference between kinetic and potential energy.
What is kinetic energy is the energy of objects in motion, while potential energy is the energy of objects that are at rest due to their position.
500
Question #5
What is mechanical waves need a medium to travel and electromagnetic waves do not need medium to travel so they can travel through space.
