Question

The energy of a wave is calculated by multiplying the frequency of the wave by the wavelength of the wave.
True
False

Answer 1

\[E=\frac{ hc }{ \lambda } =h \nu \]

Answer 2

so its fasle then right

Answer 3

yes. It would be speed of the wave.

Answer 4

To calculate the frequency of a wave, take the wave speed and divide by the wavelength of the wave.
True
False

Answer 5

that is true isnt it

Answer 6

yes it is.

Answer 7

What is the period of vibration for a wave with a frequency of 100 hertz?
100 seconds
10 seconds
0.1 seconds
0.01 seconds

Answer 8

what do you think ?

Answer 9

isnt this 0.01 senconds

Answer 10

yes.. the period is 1 divided by frequency.

Answer 11

How fast is a wave moving if it has a frequency of 10 Hz and there are 4 meters between crests?
40 m/s
34 m/s
72 m/s
64 m/s

Answer 12

i think its 40 m/s

Answer 13

\[v=\nu*\lambda \] you can calculate from here.

Answer 14

yes, that is true.

Answer 15

How does the medium move in relation to the direction of energy transport in a longitudinal wave?
perpendicular
parallel
side by side
underneath

Answer 16

what do you think ?

Answer 17

this one i have no clue of ?? :/

Answer 18

i think it would be perpendicular

Answer 19

sound wave is a longitudinal wave. when sound wave propagates in medium, all molecules that in medium move as parallel with wave. So ?

Answer 20

no nevr mind paralle right

Answer 21

Which type of wave is characterized by circular motion?
transverse wave
longitudinal wave
primary wave
surface wave

Answer 22

wouldnt that be surface wave

Answer 23

Seismic waves are mechanical waves.
True
False
