Types of Radiation
This type of electromagnetic radiation helps us see.
Visible Light.
We use visible light to model other types of radiation for this reason.
It's safe.
The name of the beam of light that travels towards the reflecting surface.
Incident ray.
The shape of a convex mirror.
Curved out; capital D.
The shape of a diverging lens.
Hourglass; bends in.
This type of electromagnetic radiation has the highest energy, and shortest wavelength.
Gamma Rays.
The Ray Model of light describes light as this.
Straight line arrows.
Refraction.
According to the Laws of Reflection for a plane mirror, the angle of reflection is always equal to this.
Angle of incident.
A converging lens bends light this way.
Towards a focal point.
This type of electromagnetic radiation helps us produce vitamin D and get a wicked tan.
Ultraviolet light.
This colour in the visible light spectrum has the shortest wavelength.
Violet.
What happens when light hits the black letters on a page that allows you to see them.
Absorption.
The spot where all reflected rays meet after bouncing off a concave mirror.
Focal point.
Light bends this way when moving from a more dense medium to a less dense one.
Away from the Normal.
These types of electromagnetic waves are used by emergency responders for communication.
Radio waves.
Photons.
The descriptor for a material that absorbs or reflects all wavelengths of light.
Opaque.
The difference between a virtual image and a real image.
Location; Real image in front of the mirror, virtual image is behind the mirror.
The shape of the lens in your eye.
Convex / Converging.
Iodine-131 is a radioisotope that gives off this type of electromagnetic radiation, used in medical imaging.
Gamma rays.
According to the photoelectric effect, blue light gives off electrons when it hits a metal surface because of this property.
High energy; higher frequency, shorter wavelength.
The imaginary line that is perpendicular to a reflective surface.
Normal.
The size of your face when looking into a convex mirror.
Larger.
The part of your eye that changes light energy into chemical energy to send signals.
Retina.
