Question

which of the following is true,if f stands for frequency,x stand for wave length and v stands for velocity of wave?
options:
1.xf/v=1
2.xv=f
3.f/v+x/v=1
4.vf/x=1​

Answer 1

Answer:

option a

because

speed=frequency×wavelength

Answer 2

Answer:xf/v=1

Explanation:

Wavelength *Frequency = Wave velocity

So let us take wavelength * frequency as x

Then velocity of wave is also x as both are equal

(Wavelength *frequency) / Wave velocity = x/x

Which is equal to one
