waves

Question 1

wave speed =

Answer 1

frequency x wavelength

Question 2

frequency

Answer 2

number of waves passing a point per second

Question 3

to measure frequency

Answer 3

measure number of waves to pass a point in 10 seconds, divide by 10
this helps with accuracy

Question 4

to measure wavelength

Answer 4

take a photo or slow mo video
measure 10 waves then divide by 10

Question 5

unit of wave speed

Answer 5

m/s

Question 6

measuring multiple waves has what effect

Answer 6

improves accuracy

Question 7

equipment of string practical

Answer 7

frequency generator
vibration generator

Question 8

how to calculate the speed of waves on piece of string

Answer 8

frequency x wavelength

Question 9

to measure frequency
string

Answer 9

generator will have number / dial that tells you the frequency of vibration generator

Question 10

signal generator =

Answer 10

vibration generator

Question 11

to measure wavelength
string

Answer 11

measure length of several using meter ruler and divide by number of waves

Question 12

several loops

Answer 12

improves accuracy

Question 13

to increase accuracy

Answer 13

avoid parallax error
not viewing ruler perpendicularly
