Equation of progressive wave is:

y=a \sin ^2 \frac{\pi}{4} \cos ^2 \frac{\pi}{4} \sin (\omega t-k x \pm \phi)

where symbols having their usual meanings then for given wave equation:

(a) Amplitude

=a \sin ^2 \frac{\pi}{4} \cos ^2 \frac{\pi}{4}

(b) Wavelength

=\frac{2 \pi}{{K}}

y=

unit of amplitude, unit of wavelength

=

unit of

x

(d) Frequency

=\frac{\omega}{2 \pi}

View answer and explanation

Correct option: C

a, b, c, d are correct

Option C (a, b, c, d are correct) is correct because all the given statements about the wave equation are true.
