Waves

QuestionAnswer
What is a wave? A distrubance that travels through a medium from one location to another location
What is a medium? A substance or material that carries the wave.
A water wave has a frequency of 2 hertz and a wavelength of 5 meters. Calculate its speed 10m/s
The frequency of wave A is 250 hertz and the wavelength is 30 centimeters. The frequency of wave B is 260 hertz and the wavelength is 25 centimeters. Which is the faster wave? A=7500 B=6500 Wave A is faster
A sound wave travels at 330 sec and has a wavelength of 2 meters. Calculate its frequency and period. F=165hz F=1/165
Can two waves interfere with eachother so that the new wave formed by their combination has NO amplitude? What interference is this? Yes Destructive interference
What happens to the amplitude of a wave as the result of Contructive Interference? Add up to make larger amplitude
What happens to the amplitude of a wave as the result of Destructive Interference? Add up to make a wave with smaller or zero amplitude
What two things determine the amount of diffraction a wave will experience? Size of opening and wavelength
Describe what you would hear as the ambulance moves away from you and what your friend would hear as the ambulance moves towards them. Your friend would hear a higher pitch and you would hear a low pitch.
What does waves carry? energy not matter
What is the definition of frequency? How often something happens
What is the definition of wavelength? length of one complete wave cycle
What is the definition of Amplitude? The maximum amount of displacement of a particle on the medium from its rest position.
What are the variables that affect reflection? Amplitude, wavespeed, direction
What does diffraction do to a wave? Makes the wave bend
What is the variable that affects Constructive Interference? Amplitude
What does a wave do to Destructive Interference? Let waves pass through eachother
Is a convex mirror a virtual image or a real image? virtual image
What other name does a convex mirror go by? Diverging mirror
