Two waves represented by y - a sin - t - kx and y - a cos - t - kx are superimposed- The resultant wave will have an amplitudeA- 2 aB- a C- -2 a D- 0

The correct option is C The two waves are obviously at a phase difference of π/2 so the resultant amplitudeA=√(a^2+a^2+2.a.acosπ/2)=√(2)a ...

Two waves represented by $y$ = $a s i n (w t - k x)$ and $y$ = $a c o s (w t - k x)$ are superposed. The resultant wave will have an amplitude

y = A sin (ω t - k x)

y = A sin (ω t + k x)

y = a s i n (ω t - k x)

y = a c o s (ω t - k x)

y = a cos (ω t - k x)

x = 0
