The properties of light

Properties of light

• light travel in a straight line
• light can be reflected
• light can be refracted

Light Travels in a straight light

• Light is a form of energy. Example of situation that show light that travel in a
• Light appears to travel from the source of light. straight line.
• Light travel in a straight line.

Simple activity to observe light travel in a straight line

straight rubber tube

bent rubber tube

Reflection of light

• Light can be reflected. Example of situation that show reflection of light
• Reflection of light occurs when incident of ray hits

a smooth and shiny surface.

Simple activity to observe reflection of light

look yourself in a mirror, and you can
see your identical twin in a mirror.

• When the light is directed onto a flat,
smooth surface like a mirror, the light is

reflected. This situation can be drawn in
the form of a ray diagram.

Refraction of Light

• Light can be refracted. Example of situation that show light can be refracted.
• Refraction of light occurs when light travels through

two different mediums, the direction of light will
change.

Simple activity to observe refrection of light

water and air are example
of medium.

the spoon look bent when the light refrect. Light from the
spoon in the water is refracted when the light travels
from water to air.
