waves

Question 1

time period

Answer 1

the time taken for one complete oscillation of a point in a wave

Question 2

progressive wave

Answer 2

waves that transfer energy from one place to another with a wavefront that travels thru the material, meaning it transfers energy without transferring material

Question 3

amplitude

Answer 3

the maximum displacement of the wave from its equilibrium position

Question 4

what is phase difference and what is it measured in

Answer 4

the amount one wave lags behind another as a portion of the wavelength, measured in rad or degree

Question 5

what is intensity

Answer 5

the amount of energy passing thru unit area per unit time or power divided by area

Question 6

how are intensity and amplitude related?

Answer 6

i is Direct proportional to a squared

Question 7

calculate the wavelength of a sound using a stationary wave

Answer 7

Find the distance between the node and the antinode and then use, half Lambda equals to distance

Question 8

What is the doppler effect and the equation for the observed frequency?

Answer 8

is an observed change in the frequency ofAnyway When the source of the wave is moving to stop when the source of the wave moves towards your server is disturbance reaches the observer in a time less than the previous disturbance

Question 9

What is the frequency change in the doctor effect dependent on

Answer 9

the frequency and wavelength change independent on the velocity of the source related to the observer
