## Mirrors

Enter the World of Mirrors

### Objectives

• Learning Target - I can describe different types of mirrors and lenses and how they form images.

• This tutorial will focus on mirrors:

Being able to describe images for concave and convex mirrors.

Next

### Graphic Organizer

• In your notebook create a t-chart similar to this example for taking notes throughout this tutorial.

Next

• It is a form of Electromagnetic Energy

• It is the only form of Electromagnetic Energy that we can see

Next

• The speed of light in a vacuum

• 299,792,458meters per second

• 186,282 miles per second

• Light travels as a electromagnetic wave

• Light can be

• Reflected

• Refracted (bent)

Next

### How do Mirrors form Image?

• Mirrors do not actually form images

• Mirrors reflect light

• Coated with a thin layer of aluminum called silvering

• Flat mirrors create identical images in size and shape

• Spherical mirrors distort images for other uses

Next

### Law of Reflection

Next

• Law of Reflection – The Angle of Incidence (incoming light) equals the Angle of Reflection (reflected light)

• When the two are equal an image can be formed

### Regular or Diffuse Reflection

• Must have Law of Reflection to obtain image – this is regular reflection

• Diffuse Reflection will not follow Law of Reflection and will not form an image

Next

### Quiz Time

Incoming Light is called?

Reflected

Incidence

### Quiz Time

Angle of Incidence = Angle of Reflection is called?

Law of Reflection

Law of Electromagnetic

### Quiz Time

Reflection from a rough surface is called?

Regular

Diffuse

### Quiz Time

Light is a form of ________ energy?

Electromagnetic

Electronic

### Quiz Time

Bending of light is called?

Reflection

Refraction

### Spherical Mirrors – Concave vs. Convex Mirror

Next

Called Diverging Mirror – Scatters Light

Called Converging Mirror – Gathers Light

### Convex Mirrors - Diverging

• Curve Outward

• Scatters Light – diverts the light

• Images appear smaller

• Allow to see images from around corners

Next

### Convex Mirrors - Diverging

Uses of Convex Mirrors

• Car rearview and side mirrors – tow mirrors

• Security mirrors – stores, hospitals, parking garages

• Bike mirrors

Next

### Concave Mirrors - Converging

• Curves Inward

• Brings light together

• Images appear upside down and smaller

• Closer the image to the mirror it gets larger and right side up

Next

### Concave Mirrors - Converging

Uses of Concave Mirrors

• Make up mirrors - Barber Shops

• Dentist

• Solar Power

• Microscopes

Next

• Now that you know the different types of spherical mirrors you can test your knowledge

• For each of the following pictures match them with the correct mirror type
