Question

if v=340m/s and frequency=850Hz then find the wavelength​

Answer 1

$\huge\underline\orange{Solution}$

Given :-

Frequency = 850 Hz

Velocity = 340 m/s

Wavelength = ?

We know that :-

$\large{\boxed{f={\frac{c}{\lambda}}}}$

Where ,

c = Velocity of light

$\large{c = 3×{10}^{8}}$

$\large{850={\frac{3×{10}^{8}}{\lambda}}}$

$\large{{\lambda={\frac{3×{10}^{8}}{850}}}}$

$\large{\boxed{\lambda=3.5×{10}^{5}}}$

Answer 2

Answer:-

Given:-

v = 340 m/s.

${\mu}$ = 850 Hz.

${\lambda}$ =?

Explanation

From the formula

v = ${\mu}$ × ${\lambda}$

v = ${\mu}$ × ${\lambda}$

${\lambda}$ = 340 ÷ 850

${\lambda}$ = 0.4metres.

$\boxed{\boxed{wavelength = 0.4 metres}}$

so,the wavelength of given frequency and velocity is 0.4 meters.
