(b) magnetic field $(1999,3 M)$
(c) displacement
(d) pressure
(1999, 3M)
Show Answer
Answer:
Correct Answer: 115.(a, b, c, d)
Solution:
Formula:
General Equation of Wave Motion:
- In case of sound wave, $y$ can represent pressure and displacement, while in case of an electromagnetic wave it represents electric and magnetic fields.
NOTE
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.
