✓
Answer
Correct option: D.
All of the above.
d
(d) In case of sound wave, $y$ can represent pressure and displacement, while in case of an electromagnetic wave it represents electric and magnetic fields.
(d) In case of sound wave, $y$ can represent pressure and displacement, while in case of an electromagnetic wave it represents electric and magnetic fields.
(In general $y$ is any general physical quantity which is made to oscillate at one place and these oscillations are propagated to other places also).
