The bending of sun's rays as they enter the raindrops formed a rainbow This is because of
the bouncing back of light as it hits the object. This is referred to as
A Reflection B. Refraction C. Transmission
D. Absorption
2
When light strikes a black surface it is absorb by the surface and nothing is reflected. This is
referred to as
A Reflection B Refraction
Transmission
D. Absorption
3
The straw when put in a glass of water will tend to bend because of the different materials
that interact with the light. This is referred to as
A Refle on B Refraction C. Transmission
D. Absorption
When light passes through a glass window, it is transmitted to the other side allowing the
light to pass through the window. This is referred to as

ANSWERS:
1. B. Refraction
2. D. Absorption
3. B. Refraction
4. C. Transmission
5. A. Transparent
6. C. Opaque
7. B. Transluscent
8. D. Visible Light
EXPLANATION:
1.&3. Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another.
2. Light absorption is a process by which light is absorbed and converted into energy.
4. Light transmission is when light travels through a medium such as glass without being reflected absorbed or scattered. When this happens light energy is not lost and can be considered 100% transmitted.
5. When light encounters Transparent materials, almost all of it passes directly through them.
6. An Opaque object is neither transparent (allowing all light to pass through) nor translucent (allowing some light to pass through).
7.When light strikes Translucent materials, like air, water and glass, only some of the light passes through them. The light does not pass directly through the materials. It changes direction many times and is scattered as it passes through.
8. Visible light is a form of electromagnetic (EM) radiation, as are radio waves, infrared radiation, ultraviolet radiation, X-rays and microwaves. Generally, visible light is defined as the wavelengths that are visible to most human eyes.
