Question

L waves ( long waves ) comes under which class body waves or surface waves .​

Answer 1

• L waves come under 'Surface Waves'.

Explanation:

Body Waves:

• Generated due to the release of energy at the focus and move in all directions travelling through the body of the Earth
• 2 types: P (Primary/ Longitudinal) and S (Seconary/ Transverse)

Surface Waves:

• Body waves interact with the surface rocks and generate new set of waves called surface waves.
• More destructive than Body waves because they cause displacement of rocks
• L waves

Denser the material, higher the velocity of the waves

Direction of waves also changes as they reflect or refract when coming across materials with different densities, reflection causes waves to rebound whereas refraction makes waves move in different directions.

Answer 2

Answer:

L waves come under surface waves.
