What is destructive interference?

Back

Destructive interference occurs when two waves meet and combine to make a wave with a smaller amplitude.

Front

What is sonar and how is it used?

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of light from a surface, while refraction is the bending of light as it passes through different media.
