Terms in this set (12)
What is the unit for frequency?
Hertz
What is frequency?
# of cycles per second
What is wavelength?
the length of one wave/cycle; can be measured as 1) crest to crest 2) trough to trough 3) same point to same point 4) one up and one down
What is the unit for wavelength?
m
An observer sitting in an anchored boat in a bay is watching waves go by. She notices that there is a distance of 10 meters between wave crests. What is the wavelength of the waves she is observing?
10 m (the distance from crest to crest)
What is the unit for speed?
meters per second
What is the formula for speed?
Speed = wavelength x frequency (note that if you're drawing a formula triangle, speed should be at the top of the triangle.)
Word problems: if you see a speed word problem that contains a wavelength measured in cm or km, what would you need to convert the unit to?
meters. (because speed is measured in meters per second)
Word problems: if you see a speed word problem that contains a frequency measured in KHz, what would you need to convert the unit to?
Hertz
Word problems: if you see a speed word problem that contains a speed measured in km/sec, what would you need to convert the unit to?
m/sec
A 5 year old is playing a game called "bobbing for apples." He notices that one of the apples is bobbing up and down rhythmically in the water one time every second. What is the frequency of the water wave?
1 Hz (one up and down motion per second)
A 5 year old is playing a game called "bobbing for apples." He notices that one of the apples is bobbing up and down rhythmically in the water every .25 seconds. What is the frequency of the water wave?
one cycle every .25 seconds; 1/.25 = 4 cycles per second
