What is the principle of superposition in wave theory?

Back

When two or more waves overlap, the resultant wave is the sum of the individual waves.

Front

What is total internal reflection?

Back

The phenomenon where light is completely reflected within a medium when it hits the boundary at an angle greater than the critical angle.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of light when it hits a surface, while refraction is the bending of light as it passes from one medium to another.

Front

What is the electromagnetic spectrum?

Back
