Concave Lenses and Ray Diagrams | GCSE Physics
Concave lenses diverge light rays and always form virtual, upright, diminished images.
What type of image is ALWAYS formed by a concave lens?
What is Concave Lenses and Ray Diagrams | GCSE Physics?
"A lens that is thinner in the middle than at the edges, used to diverge light rays."
Which of these is an example of a longitudinal wave?
If an object absorbs more radiation than it emits, its temperature will ____.
Arrange these EM waves in order of INCREASING energy: Radio, Visible, UV, Gamma.
The distance between the same point on two adjacent waves is called the ____.
Diverging Light
Parallel rays spread out as if coming from the principal focus.
Images formed are always virtual (cannot be projected onto a screen).
The image is always closer to the lens than the object.
Used to correct short-sightedness (myopia).
Visual Distinction: Concave lenses "cave in" at the middle. They spread light out like a cave opening sweeps the eye!
