NO. I CANT LAUGH YET. IVE GOT TO HOLD IT IN.

Question 1

Wave

Answer 1

a propagating disturbance that transfers energy through a medium without physically transporting the medium itself

Question 2

Medium

Answer 2

a material that moves energy or light from one substance to another, or from one location to another, or from one surface to another

Question 3

Transverse Wave

Answer 3

a wave that oscillates perpendicularly to the direction of the wave’s advance

Question 4

Compressional Wave

Answer 4

a wave where the movement of the medium, or the vibration or disturbance within the medium, is in the same or parallel direction as that of the motion of the wave

Question 5

Sound Waves

Answer 5

longitudinal waves that travel through a medium like air or water

Question 6

Water Waves

Answer 6

a combination of longitudinal and transverse waves and are surface waves

Question 7

Seismic Waves

Answer 7

vibrations in the earth that transmit energy and occur during seismic activity

Question 8

Crests

Answer 8

the highest point of the wave

Question 9

Troughs

Answer 9

the minimum or lowest point of the wave

Question 10

Refaction

Answer 10

the bending of a wave, like light, as it passes from one medium to another, causing a change in its direction due to a change in its speed as it enters a new medium with a different density

Question 11

Wavelength

Answer 11

the distance between two consecutive identical points on a wave

Question 12

Frequency

Answer 12

the number of waves that pass a given point in one second

Question 13

Amplitude

Answer 13

the maximum displacement of a wave or vibrating object from its equilibrium position

Question 14

Refraction

Answer 14

the change in direction of a wave passing from one medium to another caused by its change in speed

Question 15

Diffractions

Answer 15

the bending or spreading out of waves as they pass through an opening or around an obstacle

Question 16

Interference

Answer 16

the superposition of waves, causing an increase or decrease in the amplitude of the resulting wave

Question 17

Standing Wave

Answer 17

a wave that oscillates in time but whose peak amplitude profile does not move in space

Question 18

Resonance

Answer 18

the occurrence of a vibrating object causing another object to vibrate a higher amplitude

Question 19

Eardrum

Answer 19

a thin membrane located in the outer ear that responds to sound waves by vibrating

Question 20

Cochlea

Answer 20

the spiral-shaped structure located in the inner ear that functions as a key component of the hearing process

Question 21

Intensity

Answer 21

the amount of energy transferred per unit area

Question 22

Loudness

Answer 22

the property of sound which is used for differentiating between the loud and faint sounds

Question 23

Decibel

Answer 23

a unit of measurement used to express the ratio of a physical quantity, usually sound intensity or power

Question 24

Pitch

Answer 24

the measure of sound frequency expressed in terms of Hertz

Question 25

Ultrasonic

Answer 25

sound waves with a vibration frequency greater than 20,000 Hz, beyond the range of human hearing

Question 26

Doppler effect

Answer 26

the increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move towards (or away from) each other

Question 27

Overtone

Answer 27

any resonant frequency that is higher than the fundamental frequency of a sound

Question 28

Acoustics

Answer 28

the science concerned with the production, control, transmission, reception, and effects of sound

Question 29

Echolocation

Answer 29

the use of sound waves to determine the location of objects

Question 30

Sonar

Answer 30

technique for detecting and determining the distance and direction of underwater objects by acoustic means
