Properties of Light
This is how light travels through empty space.
What is in straight lines?
The part of the eye that regulates how much light enters.
What is the pupil?
A mirror type that reflects light back completely.
What is a regular mirror?
The percentage of light that is reflected and transmitted by a one-way mirror in normal conditions.
What is 50% reflected, 50% transmitted?
A common object that uses principles of light reflection to produce images.
What is a television?
The process where light bends as it passes through a medium like water.
What is refraction?
The organ that works with the eye to process light signals.
What is the brain?
A mirror type that reflects some light and allows some to pass through.
What is a one-way mirror?
A term for light passing through a material.
What is transmission?
The name of the phenomenon where light spreads in all directions when hitting a rough surface.
What is scattering?
The term for light being bounced off a surface.
What is reflection?
This is how the image of an object appears on the retina before being processed by the brain.
What is upside down?
A scenario where light reflects at the same angle it hits the surface.
What is regular reflection?
The behavior of light as it interacts with water.
What is refraction?
A material that completely blocks light.
What is opaque
A material that transmits more light than it reflects.
What is glass or plastic?
The effect on the pupil when a room's light intensity increases.
What is narrowing?
The reason Pete can be seen by the teacher through a one-way mirror.
What is the stronger light from Pete’s room reflects off the mirror to the teacher?
Light needs to do this to allow a teacher to see a student behind a one-way mirror.
What is reflect off the student and transmit through the mirror?
The part of the light wave that determines brightness.
What is amplitude?
The way light behaves when it hits a material that absorbs some light and lets the rest through.
What is transmission?
Why is the sun perceived as brighter than a computer screen?
What is the brain responds to the stronger signal from the sun?
This factor determines the behavior of light on a mirror's surface.
What is the material of the mirror?
The reason why light seems different between two rooms with varying brightness.
What is the stronger light reflects better?
A factor that affects light's ability to pass through or reflect off materials.
What is the material's transparency or reflectivity?
