A harmonic wave is travelling along a rope .The source generating the waves completes 50 to and fro motions in 25 s.A trough travels 2m in 4s. Сalculate wavelength ,frequency and speed

Melany Duarte

Solution:
frequency = 50/25 = 2Hz
wavelength = speed of light $÷$ freqency
$=3×{10}^{7}÷2$
Now, $=1.5×{10}^{7}m$
speed = 2m $÷$ 4s
