Mirrors Part 1

• Regular Reflection: occurs when parallel rays of light hit a smooth surface. All rays reflect at the same angle and produce a clear image.

• Diffuse Reflection: occurs when parallel rays of light hit an uneven surface and reflect at diferent angles producing an unclear image.

• Top Image: Regular Reflection

• Bottom Image: Diffuse Reflection

• An Image is a copy of the object formed by reflected or refracted light rays.

• There are two types of Images: Virtual and Real

• Virtual images are right side up

• Virtual images have the left and right side reversed.

• Virtual images form where light seems to come from (like behind the mirror)

• Virtual images cannot be projected onto a screen

• Real images are upside down

• Real images form at the focal point where light rays meet

• Real images can be projected onto a screen

There are three types of mirrors that we will discuss: Plane, Concave, and Convex.

Flat mirrors like the one you have in your bathroom. Creates an image that is:

Virtual and Same Size as the object

• Curved (like the inside of a spoon)

• Real or Virtual Images

• (Virtual Image when object is between the focal point and the mirror)

• (Real Image when object is beyond the focal point)

• Size can be larger, smaller, or same (the closer to the focal point the larger it will appear)

• virtual image smaller than the object

• advantage is that it allows you to see a larger area but disadvantage is the image is reduced in size.

• Used in driver side mirrors and on ceilings in stores for security.

• There are two types of reflections: Regular and Diffuse

• There are three types of mirrors (Plane, Concave, and Convex)

• These mirrors can produce two types of images: Real or Virtual

• Virtual Images are right side up

• Real Images are upside down

Draw the image then share with class
