Taskl. Read the paragraphs.
What Causes Reflections?
a) Light from the sun or a light bulb moves in straight waves. When
the light waves hit an object, they bounce off of it. This action is called
reflection. For most objects, the light bounces in many directions at the
same time. When this happens, it allows us to see the object. A picture of
the object is sent to the brain from the eye. The brain helps us understand
what we see.
b) Light waves also bounce when they hit a smooth, shiny surface.
Hitting a surface like a mirror makes the light waves bounce directly
back to your eyes. This movement allows you to see yourself. It creates a
reflection. You see the objects around it instead of the mirror itself.
Anything shiny may act like a mirror when the light hits it. Have you ever
seen your face reflected in the rounded side of a pot or pan? You can even
see reflections on the surface of water if it is smooth and still. You have
probably seen beautiful pictures of mountain scenes. Often the mountains
and sky are reflected on the smooth surface of the lake.
c) Water and glass have a special ability. They can refract, or bend,
light. That's why a spoon in a clear glass of water will look bent when it
really is not. The ability of glass to refract light has given us some useful
products. Eyeglasses help us see clearly. Magnifying glasses enlarge our
view of an object.
Match the titles 1-3 with paragraphs a-c.
1. Properties of reflection in other objects.
2. The characteristic of the word reflection.
3. What is the result of movement of light waves?
Underline the word from the text by its definition.

1. An object that people use to look at themselves in.
2. This thing people use when they have a bad sight.
3. This is an ability of the light waves to fall into the objects and jumps

back from them.
4. An object that people can see during the day.
5. This fluid plays an important role in the life of all organisms that

live on planet Earth.
