1.

What are vibrational frequencies that range beyond 20,000 Hz?

a)

Ultrasonic frequencies

b)

Infrasonic frequencies

2.

What part of the ear collects sound waves and focuses them into the ear canal?

(a)  

3.

What type of waves are sound waves?

a)

Electromagnetic waves

b)

Mechanical waves

4.

Vibrations of the medium create a series of crest and trough which results to transverse waves

a)

True

b)

False

5.

Sound is the slowest in matter that is closely packed like solid and fastest in gas.

a)

True

b)

False

6.

High temperature brings much faster sound. Increased humidity, on the other hand makes sound travel slower.

a)

True

b)

False

7.

As pressure is increased, speed is also increased.

a)

True

b)

False

8.

Solid tend to be highly elastic than gases and thus sound travel fastest in solids.

a)

True

b)

False

9.

Humid air is more massive and is more inert than dry air. This condition brings lesser molecular interactions and eventually slower sound.

a)

True

b)

False

10.

The higher the frequency the higher the pitch of the sound produced.

a)

True

b)

False

11.

Frequencies beyond the upper limit of audible sound for humans is called infrasonic.

a)

True

b)

False

12.

High amplitude waves are intense and are sensed as loud sound.

a)

True

b)

False

13.

A special sound that forms patterns and are appealing to our sense of hearing.

(a)  

14.

Speed of sound is dependent on factors like temperature, humidity, and air pressure (atmospheric pressure).

a)

True

b)

False

15.

What is the unit of intensity level of sound?

(a)  

16.

White and Black are considered as colors of light.

a)

True

b)

False

17.

Light accordingly has a wave-like nature and particle-like nature.

a)

True

b)

False

18.

Light is a mechanical wave.

a)

True

b)

False

19.

Light travels in a straight line path in a particular medium.

a)

True

b)

False

20.

Blue light is being refracted more than the other color lights and thus it appears to be bent.

a)

True

b)

False
