Optic
Concave lens diminishes or magnify?
Diminishes
What is the wavelength?
It is the length of a full cycle of a wave (the distance from crest to crest or from trough to trough). It is measured in meters and the symbol is lambda (λ)
What do concave mirrors do?
Converge
What is the incident ray?
The light coming in
What is a real image?
An image that exists in space
A convex lens diminishes or magnify?
Magnify
What is the amplitude?
Define it and draw an example. It is the 'size' of a wave. It is measured from the equilibrium position (or the central line) to the crest - NOT from the crest to the trough.
What do convex mirrors do?
diverge
What is the reflector ray?
The light coming out
What is an example of a real image?
A projector
If you have hyperopia, what lens do you need?
Convex
There are two types of waves:
Transverse
Light
What happens if you pass the focus point in a concave mirror?
You see the image upside down
What is the line 90 degrees from the reflected object?
Normal
What is a virtual image?
An image formed by the eye from the light rays appearing to diverge from an optical component.
If you have myopia, what lens do you need?
Concave
What is the only example of Longitudinal waves?
Sound
Where can you see a convex mirror?
Rear-view mirror in a car
In most cases, what is light reflecting off?
Plane mirror
What is an example of a virtual image?
Mirrors
how does fiber optics work?
it sends information coded in a beam of light down a glass or plastic pipe.
Waves only transport….
Energy
where can you see a concave mirror?
Spoon
What is the law of reflection?
The angle of incident is equal to the angle of reflection
A ball is a virtual image (true or false)?
False
