Question

If a radio station transmits at 219 m wavelength and 1370 kHz frequency, calculate velocity of waves.

Answer 1

$<b><i>$
SOLUTION !

Wavelength (v) = 219 m
frequency (f) = 1370 kHz

= 1370 × 1000 Hz
= 1370000 Hz

we know,

v = f × v

Putting the given values in the above relation,

we get

v = 1370000 Hz × 219 m

v = 300030000 m/s

v ≈ 3 × 10⁸ m/s

thus, the velocity of waves is 3 × 10⁸ m/s.



glad help uh
thanks

Answer 2

Explanation:

v = 219

f = 1370 kHz

1370 ×1000 = 1370000 Hz

we know that v = v × f

1370000 × 219 = 300030000m/s
