EM Radiation and Waves
The highest point of the wave is known as this
What is the crest
An object that allows some light to transmit through and some light to get reflected back or get absorbed is known as this
What is translucent
Smooth, flat mirrors are known as this
What are plane mirrors
A lens is made up of this type of material (allows all light to transmit through)
What is transparent
The height of the wave is known as this
What is amplitude
The electromagnetic radiation with the lowest wavelength/ highest frequency
What is gamma radiation
Reflection off _____ surfaces causes light rays to scatter in different directions and makes the object visible to us.
These mirrors allow light to diverge (move away)
What are convex mirrors
Images form in this region of the eye
What is the retina
In a dark room, our pupils do this to help us see
What is dilate
The distance from crest to crest is known as this
What is wavelength
Explain how we see the yellow skin of a banana
Yellow light is reflected, all other colours are absorbed
Images in these types of mirrors appear smaller and closer to the mirror than in real life
What are convex mirrors
This type of lens is thinner in the middle than at the edges
What are concave/ diverging lenses
This colour of visible light has the longest wavelength
The electromagnetic radiation that is used to tan and help solve crimes by finding evidence
When light is reflected off a smooth surface, the angle of incidence should equal this
What is the angle of reflection
When object is placed close to a concave mirror, the image is this
What is larger and upright
This type of lens is used to help correct nearsightedness
What is a concave lens.
Magnifying glasses use this type of lens
What is a convex lens
The Sun is a source of these electromagnetic radiations
As light refracts into a second medium, the refracted ray is closer to the normal than the incident ray. What does this say about the second medium?
Light moves slower in the second medium (and is more dense than the first medium)
When an object is placed far away from a concave mirror the image is this
This is the white part of the eye that surrounds the cornea
What is the sclera
This happens to visible light when it hits an object that is black
All light is absorbed
