Equation of progressive wave is:

y=asin⁡2π4cos⁡2π4sin⁡(ωt−kx±ϕ)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 =asin⁡2π4cos⁡2π4=a \sin ^2 \frac{\pi}{4} \cos ^2 \frac{\pi}{4}

(b) Wavelength =2πK=\frac{2 \pi}{{K}}

(c) Unit of y=y= unit of amplitude, unit of wavelength == unit of xx

(d) Frequency =ω2π=\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 statements about the amplitude, wavelength, units, and frequency are accurate based on the given wave equation.
