In a wave motion `y= a sin(kx-omegat)`, y can represent:
(a) electric field , (b) magnetic field , (c) displacement , (d) pressure

Options

A. electric field
B. magnetic field
C. displacement
D. pressure

Answer

A, B, C, D

Explanation

The wave motions `y=a sin(kx-omegat)` reprsents
(a) electric filed in electromagnetic wave (b) magnetic field in electromagnetic wave y is changed to E,B,y ,`p_0` respectively in each case
(c)displacement in sound wave
(d) presure in sound wave
Hence all the four option are correct.
