Which light has the longest wavelength?

Which light has the shortest wavelength?

The bouncing of light on a surface

• Reflection

• Refraction

It travels in straight path, has a speed of about 300 000

kilometers per second (km/s).

It is slowed down a bit and gives the impression of bending

when it travels from a less dense medium to a denser medium such as

from a vacuum to air or from air to water.

• Reflection

• Refraction

materials allow most of light to pass directly through them.

• Transparent

• Translucent

• Opaque
