A wave travelling along the x-axis is described by the equation

y\left( {x,t} \right) = 0.005\,\,\,cos\left( {\alpha x - \beta t} \right)

. If the wavelength and the time period of the wave are

0.08{\mkern 1mu} {\mkern 1mu} \,\,m\,\,\,and\,\,2.0{\mkern 1mu} {\mkern 1mu} s

, respectively, than

\alpha \,\,and\,\beta

in appropriate unit are

View answer and explanation

Correct option: A

a = 25.00\pi ,\mathrm{ }\beta \mathrm{ }\pi

Option A (

a = 25.00\pi ,\mathrm{ }\beta \mathrm{ }\pi

) is correct because it correctly calculates the values of

\alpha

and

\beta

using the given wavelength and time period.
