Light
Two answers required: Material that lets light pass through in a straight, Material that absorbs the light not letting it pass through.
What are, Transparent and Opaque?
Electromagnetic with very short wavelengths. Are used for looking at bones inside the body.
What are X-Rays?
The bouncing back of particles or waves.
What is reflection?
The change in direction of a wave as it crosses through different materials in which the wave travels at different speeds.
What is Refraction?
Any bending of a wave by means other than reflection or refraction
What is Diffraction?
Formed where light rays cannot reach.
What is Shadow?
Energy moving through space as invisible waves.
What is Radiation?
The term to describe when all of the particles or waves are reflected.
What is Totally Reflected?
The law that states that the angle of incidence is equal to the angle of reflection.
What is the Law of Reflection?
A piece of glass that bends parallel light rays into crossing, creating an image.
What is a Lens?
Partial Shadow, a partial blocking of light.
What is a Penumbra?
What is Non-Ionizing Radiation?
An object that reflects an image using light, often associated with convex and concave.
What is a Mirror?
A wave bend caused by the part of the wave closer to the ground speeding up due to hot air.
What is Atmosphere Refraction?
The separation of light into colors arranged according to their frequency.
What is Dispersion?
Created when electrons and atoms vibrate more than one million times each second.
What is Light?
Position of medium when no wave is travelling through.
What is a Rest/Home Position
The term to describe when only some of the particles or waves are reflected.
What is Partially Reflected?
The idea that wave fronts are made up of smaller wave fronts.
What is the Huygens' Principle?
What are Diverging and Converging Lenses.
DAILY DOUBLE: The effect that causes light to sometimes knock electrons out of a substance.
What is the Photoelectric Effect?
What is Ionizing Radiation?
The term to describe the reflection of light in which the light reflects in many different directions.
What is Diffuse Reflection?
DAILY DOUBLE: The reason a beam of light can't enter from a glass, and instead is reflected.
What is Total Internal Reflection?
Waves that spread out from a point source, which produce secondary wavelets.
What are Light Waves?
