What does opaque mean?

Back

Not allowing any light to pass through.

Front

Why does a straw look bent in water?

Back

It looks bent because the water refracts light, causing the stem to look bent.

What is the difference between transparent, translucent, and opaque materials?

Back

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

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 critical angle?

Back

The minimum angle of incidence at which total internal reflection occurs.

Front

How does light behave when it passes from air into water?

Back

Light slows down and bends towards the normal line due to refraction.
