Waves Unit- Part Three (re:2024)

Front

What is Diffusion?

Back

Diffusion is the process where parallel rays of light hit a bumpy surface, causing them to scatter.

Front

What does diffraction of an electromagnetic wave mean?

Back

Diffraction refers to the bending of waves around barriers.

Front

How does the medium affect the speed of light?

Back

In different media, gas is the fastest, liquid is slower, and solid is the slowest.

Front

What is a Transparent material?

Back

A transparent material allows light to pass through it without significant scattering.

Front

What is Diffused reflection?

Back

Diffused reflection occurs when light reflects off a rough and/or uneven surface.

Front

What is the angle of incidence?

Back

The angle of incidence is the angle between the incoming ray and the normal to the surface at the point of incidence.

Front

What is the angle of reflection?

Back

The angle of reflection is the angle between the reflected ray and the normal to the surface at the point of reflection.

Front

What happens to light when it enters a different medium?

Back

When light enters a different medium, it bends due to a change in speed.

Front

What is the difference between Transparent, Translucent, and Opaque materials?

Back

Transparent materials allow light to pass through clearly, translucent materials allow some light to pass but scatter it, and opaque materials do not allow light to pass through.

Front

What is the Law of Reflection?

Back

The Law of Reflection states that the angle of incidence is equal to the angle of reflection.
