Question

when medium changes which of the following quantity of a wave does not - amplitude, frequency, speed, wave length

Answer 1

frequence does not change

Answer 2

@ why so?

Answer 3

u know velocity of sound wave decreases during passing through water

Answer 4

velocity of sound is lower in water than air

Answer 5

Frequency is a feature of the supply. it does not change unless supply changes.

Answer 6

ya u r right

Answer 7

but wavelength will b decreaes into water than air

Answer 8

@shamim u r right but i had asked 4 unchanging quantity amplitutde a.w.a wavelength will change

Answer 9

For EM wave, n=c/v

where,

n=refraction index
c=speed of EM wave
v=speed of the wave that is in the medium has refraction index n.

Answer 10

exactly
