Answer 9

C) Static

Question 10

What is the principle of superposition?

Answer 10

The principle that when two or more waves overlap, the resulting wave is the sum of the individual waves.

Question 11

Answer 11

False

Question 12

What phenomenon occurs when waves change direction due to a change in medium?

Answer 12

Refraction

Question 13

Fill in the blank: The maximum displacement of a wave from its rest position is called the _____ .

Answer 13

amplitude

Question 14

What is a standing wave?

Answer 14

A wave that remains in a constant position and does not travel through space.

Question 15

Multiple Choice: Which wave property is measured in decibels? A) Frequency B) Amplitude C) Wavelength D) Speed

Answer 15

B) Amplitude

Question 16

What is the Doppler effect?

Answer 16

The change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source.

Question 17

True or False: Waves can interfere constructively or destructively.

Answer 17

True

Question 18

What is the term for the bouncing back of a wave when it hits a barrier?

Answer 18

Reflection

Question 19

Fill in the blank: The time it takes for one complete wave cycle to pass a given point is called the _____ .

Answer 19

period

Question 20

What is the relationship between frequency and period?

Answer 21

C) Light

Question 22

What is wave interference?

Answer 22

The phenomenon that occurs when two or more waves meet while traveling along the same medium.

Question 23

True or False: The speed of sound is faster in air than in water.

Answer 23

False

Answer 25

mechanical

Question 26

What is the difference between transverse and longitudinal waves?

Answer 26
