Mathematical difference between frequency and period

Answer 16

They are inverses of each other

Question 17

Frequency

Answer 17

How many cycles of an oscillation occur per second

Question 18

Period

Answer 18

Amount of time it takes a wave to vibrate one full cycle

Question 19

What is the speed of sound in air at 20 degrees Celsius

Answer 19

343m/s

Question 20

How do you determine the speed at any other degree Celsius

Answer 20

You add 0.6 for every increase in 1 degree celsius

Question 21

What is the major difference between S and P waves

Answer 21

P waves can travel through liquids, solids, and gases
S waves can only travel through solids (stops at outer core)

Question 22

Doppler effect

Answer 22

The change in frequency of sound caused by movement of either the source, the detector, or both

Question 23

What are four applications of the Doppler effect

Answer 23

Speed of baseball/cars
Astronomers
Physicians
Bats

Question 24

Pitch

Answer 24

The highness or lowness of a sound

Question 25

Loudness

Answer 25

The intensity of the sound as perceived by the ear and interpreted by the brain

Question 26

How are pitch and loudness related to waves

Answer 26

They both relate to waves because pitch relates to the frequency and the loudness related to the amplitude

Question 27

What is wavelengths symbol named

Answer 27

Lambda

Question 28

What is wavelength measured in

Answer 28

Meters

Answer 43

Ultraviolet Waves

Question 44

Sound Wave

Answer 44

A pressure oscillation that is transmitted through matter

Question 45

Sound is what type of wave

Answer 45

Longitude wave

Question 46

Sound level

Answer 46

Measure of intensities on a logarithmic scale

Question 47

Decibel

Answer 47

Unit of measurement for sound level

Question 48

Two characteristic that are affected by the medium through which sound passes

Answer 48

Velocity and wavelength

Question 49

Two characteristics that not NOT affected by the medium through which sound passes

Answer 49

frequency and period

Question 50

Blue shifted

Answer 50

When light source approached observer, there is an increase in measured frequency, so wavelength of light shortens

Question 51

Red shifted

Answer 51

When a light source recedes from observer this is the decrease in measured frequency, so wavelength lengthens.
