Why does light bend when it goes through glass at an angle?
It goes faster, causing the beam to bend
It goes slower, causing the beam to bend
Light can't pass through glass
Light travels at the same rate through any object
4. Tom wants to show his friend his new magical trick. He challenged his friend that he
can make his pencil appear broken without actually breaking the pencil. To
demonstrate this, Tom placed the pencil in a class of water and told his friend to take
a look through the glass and the water from the side. Tom felt disappointed when his
friend said it was not a trick and that he knows exactly what happened. Which best
described Tom’s “trick”?
A. Refraction
B. Absorption
C. Transmission
D. Scattering
5. A mechanical wave can pass through a solid, liquid or gas medium. However, the
properties of the wave might change as it passes from one medium to the next. What
happens to the speed of the wave as it passes from a solid to a gas?
A. It slows down
B. It speeds up and then slows down
C. It speeds up
D. It remains the same
6. Which of the following terms describes the number of waves that can be produced
over a given time?
A. Wavelength
B. Pitch
C. Frequency
D. Amplitude
7. Which of the following reasoning explains why the sound of an airplane high in the
sky is heard well after the airplane has passed?
A. The airplane is too far up in the sky
B. The sound travels slower than the airplane
C. Sound waves travel slower in air than in liquids or solids
D. The frequency of the sound from the airplane is too low
8. TRUE OR FALSE: In general waves travel fastest in a solid medium because the
particles are closely arranged together. (1 point).
9. TRUE OR FALSE: Light travels faster in solid glass as it does in in liquid water. (1
point).

1. D
2. B
3. B
4. A
5. A
6. C
7. C
8. TRUE
9. FALSE
10. SHORT ANSWER:
Transparent matter transmits light all the way through.
Translucent matter transmits light but not all the way through. It causes the light to scatter
in all direction causing distortion.
Opaque matter does not allow light to pass through, instead, the light is reflected or
absorbed.
