Question 1

What medium means

Answer 1

Answer: A material in which a wave travels

Question 2

Why sound travels at different speeds in different materials

Answer 2

Because solids, liquids, and gasses have very different densities

Question 3

Location of eardrum

Answer 3

Answer: it separates the outer and middle ear, it is located under the hammer.

Question 4

Given image of different sound waves, you need to identify which one has the highest frequency

Answer 4

You can tell by seeing which wave has more crests than the other.

Question 5

Which property of a sound waves determines how close the particles are in the compression region.

Answer 5

Answer is amplitude

Question 6

Meaning of resonance

Answer 6

Answer: is an increase in amplitude, caused by an object vibrating at same freq. absorbs energy from a nearby object vibra. at same freq.

Question 7

Examples of Longitudinal Waves:

Answer 7

Sound Waves, spring vibration, ultrasound etc.

Question 8

Transverse wave examples

Answer 8

Light waves, ripples on the surface of water, electromagnetic waves, seismic waves

Question 9

echolocations

Answer 9

is the process an animal uses to locate an object by means of reflected sounds.

Question 10

sonar

Answer 10

is a system that uses the reflection of sound waves to find underwater objects

Question 11

know this

Answer 11

Distance= speed x time

If questions mention the wave bouncing back to you then divide time by 2 before multiplying since you are trying to find how far the wave travels before bouncing back.
(Distance= speed x (time/2)

Question 12

speed

Answer 12

Speed= frequency x Wavelength

Question 13

frequency

Answer 13

Frequency= speed/wavelength

Question 14

wavelength

Answer 14

Wavelength= speed/frequency

Question 15

which prop of sound is the sound is the number of wavelengths that pass by a point each second.

Answer 15

freqency

Question 16

which property is this, The perception of how high or low something is

Answer 16

pitch
