A wave disturbance in a medium is described by `y(x, t) = 0.02 cos((50pit + (pi)/(2))cos(10pix)` where `x and y` are in meter and `t` is in second`

A wave disturbance in a medium is described by y(x,t) = 0.02 "cos"(50pit + (pi)/(2))"cos"(10pix) where x and y are in metre and t is in second . Which of the following is correct ?

A wave disturbance in a medium is described by Y=0.02 cos( 50 pi t + pi/2) cos pi x . Where x and y are in m and t in sec. The values in Column-II are in SI units.

The disturbance of a wave is represented by the equation y(x, t) = 0.04 cos (100 pi t + (pi)/(2)) cos (20 pi x) x, y are in m and t is in second. Find the positions at which (a) a node will be formed. (b) an antinode will be formed. Also find speed and wavelength of the wave.

The equation of a wave distrubance is a given as y= 0.02 sin ((pi)/(2)+50pi t) cos (10 pix) , where x and y are in metre and t is in second . Choose the correct statement (s).
