5.3 Wave Properties: Reflection

Question 0

What is the term for the ray that goes towards a mirror?

Answer 0

The ray that goes towards a mirror is called the incident ray.

Question 1

Why do we see an image in a mirror?

Answer 1

We see an image in a mirror because of the reflection of light.

Question 2

What is the incident ray?

Answer 2

The incident ray is the ray that goes towards a mirror.

Question 3

What is the term for the ray that goes away from a mirror?

Answer 3

The ray that goes away from a mirror is called the reflected ray.

Question 4

What is the reflected ray?

Answer 4

The reflected ray is the ray that goes away from a mirror.

Question 5

What is the term given to the angle that is between the incident ray and the normal?

Answer 5

The angle between the incident ray and the normal is the angle of incidence.

Question 6

What is the angle of incidence?

Answer 6

The angle of incidence is the angle that is between the incident ray and the normal.

Question 7

What is the term given to the angle that is between the reflected ray and the normal?

Answer 7

The angle that is between the reflected ray and the normal is the angle of reflection.

Question 8

What is the angle of reflection?

Answer 8

The angle of reflection is the angle that is between the reflected ray and the normal.

Question 9

What is the normal?

Answer 9

The normal is a line perpendicular to the mirror at the point when the incident ray hits the mirror.

Question 10

What is the line perpendicular to the point at which the incident ray hits the mirror called?

Answer 10

The line that is perpendicular to the mirror at the point when the incident ray hits the mirror is called the normal.

Question 11

What do the angle of incidence and the angle of reflection have in common?

Answer 11

The angle of incidence and the angle of reflection are equal.

Question 12

Which two angles involved in reflection are equal?

Answer 12

The two angles involved in reflection that are equal are called the angle of incidence and the angle of reflection.

Question 13

What size is the image created in a plane mirror?

Answer 13

The image created in a plane mirror is always the same size as the object.

Question 14

Is the image created in a plane mirror always upright?

Answer 14

Yes, the image created in a plane mirror is always upright.

Question 15

What distance behind a plane mirror is the image compared to the object in front?

Answer 15

The image created in a plane mirror is always the same distance behind the mirror as the object is in front.

Question 16

Is the image created in a plane mirror real or virtual?

Answer 16

The image created in a plane mirror is always virtual.

Question 17

What is the definition of a real image?

Answer 17

A real image: Can be formed on a screen. This is because rays of light that produce the image do actually pass through it.

Question 18

What is the definition of a virtual image?

Answer 18

A virtual image: Can’t be formed on a screen. This is because the rays of light tags produce it only appear to pass through it.

Question 19

What type of image can be formed on a screen and why?

Answer 19

A real image can be formed on a screen. This is because rays of light that produce the image do actually pass through it.

Question 20

What type of image cannot be produced on a screen and why?

Answer 20

A virtual image cannot be formed on a screen. This is because the rays of light that produce it only appear to pass through it.
