Question
Describe the three types of earthquake waves.
Solution
The three types of earthquake waves are described below:
(i) ‘P’ or longitudinal waves or primary waves - These waves travel in the direction of their movement. They can travel through solid as well as liquid matter.
(ii) ‘S’ or transverse or secondary waves - These waves travel at right angle to the direction of their oscillation. They can travel in solid media only.
(iii) ‘L’ or Long Waves - These are surface waves. These do not go deep into the earth.
