Ray Diagrams - Lenses

What type of lens is shown here?

• diverging

• converging

What does a diverging lens do?

• spreads the rays apart

• brings the rays together

• keeps the rays straight

• polarizes the rays

What type of lens is shown here?

• converging

• diverging

What wave behavior is described as the bending of a wave (e.g. light) as it moves from one medium to another?

• refraction

• diffraction

• resonance

• Doppler Effect

What are  types of images that come from the bending of light as it passes through a lens?

• real and virtual

• compression and rarefaction

• real and unreal

• diffraction and reflection

What is the importance of ray diagrams?

• It's a way to figure out where an image is when light is refracted.

• It helps us determine whether an image that we are seeing is a real image or a virtual image.

How do we know that the image will be upside down?

• The rays are converging

• the rays are diverging

• the rays are not refracted

• the rays go through the focal point

Which of the following is not true about virtual images?

• It forms upside down.

• It forms on the same side as the object 

• It forms when the image is inside the focal point.

• It forms because the rays diverge after passing through the lens.

How do rays passing through a diverging lens differ from rays that pass through a converging lens?

• The rays spread out as they pass through

• They create true images

how do we find the image from a diverging lens?

• find where the lines intersect

• on the other side of the diverging lens
