It is a law that states that the incident angle and the reflected angle are the exact same.
100
What is wavelength?
The distance between one point of a wave to the other.
100
Does sound go slower or faster in dense objects? And why?
Faster, because the molecules are close together and the vibrations pass through more easily.
100
What are the three primary regions of an ear?
The outer, Middle and Inner ear.
100
What do people use when partial hearing is lost? And how does it work?
People usually use a hearing aid, which works by amplifying incoming sound waves closer to the ear.
200
What is the difference between an Incident angle and a Reflected angle? And what is the normal angle?
The incident angle is the angle of the light coming in, reflected is the angle of the light that is reflected. The normal angle is the line perpendicular to the plane.
200
What happens when all colors of light are combined?
You create white light.
200
What is frequency measured in? And what is the abbreviation? (e.g Centimeters=cm)
Frequency is measured in Hertz, its abbreviation is Hz.
200
What is the loudness of sound measured in? And what is its abbreviation?
The loudness is measured in decibel, its abbreviation is dB.
200
What are torn ear drums less sensitive too?
Air pressure waves.
300
What is the difference between a Concave, Convex and Plane mirror?
Concave reflects light towards a focus, Convex reflects light outwards and Plane reflects light directly.
300
What happens when all colors of dyes are combined? And why does this happen?
You create the color black, this occurs because dyes absorb colors and reflect only one, when more dyes are added the more colors are absorbed.
300
How fast does sound travel in the air?
330 meters per second.
300
What type of sounds have the potential to tear the ear drum?
Sounds that are high in the decibel scale.
300
What is the name of the machine that measures sound?
Oscilloscope.
400
What is the Transmission?
When a light filter absorbs all wavelength of color, and lets through only specific ones.
400
What are the primary colors of light and what do they make when they are combined?
Green, Blue, Red
Green+Blue=Cyan
Blue+Red=Magneta
Green+Red=Yellow
400
What are the terms use to describe the parts of a sound wave?
Amplitude, Wavelength, Crest, Trough.
400
What parts of the ear are in the outer ear section?
Auricle/Pinna and the ear cannal.
400
What is the crest? And what is the trough?
Crest: Highest point of a wave.
Trough: Lowest point of a wave
500
What is a Ray Diagram?
A diagram that shows the path of light before it hits your eye, when you're trying to look at something.
500
How many colors is white light made up of and what are they?
