Wavelength

Question 10

A stationary wave pattern formed in a medium when two sets of identical wave passes through the medium in opposite directions

Answer 10

Standing wave

Question 11

It occurs when a wave strike an object or comes to a boundary or another medium and is at least diverted back into the original medium.

Answer 11

Reflection

Question 12

It occurs when a wave crosses a boundary into another medium its speed generally changes because the new material has a different characteristic
