Sound
100
Increasing the frequency does what to the pitch?
Increases the pitch
100
A wave made from vibrating electrolmagenic fields
Electromagnetic waves
100
An object that does not let light pass through
Opaque
100
The Bending of Light as it passes through a medium
Refraction
100
When light rays bounce off from smooth opaque objects
Reflection
100
The opening that allows light to enter
Pupil
200
Section of the sound wave where the particles are close to each other
Compression
200
Increasing the amplitude does what to the volume?
Increases the volume
200
A type of wave that vibrates perpendicular to its dieration
Transverse
200
An object that lets some light pass through
Translucent
200
The measure of how much a medium bends the light
Refractive Index
200
The imaginary line that is perpindicular to the mirror
Normal
200
Controls how much light enters
Iris
300
Section of the sound wave where there are less particles
Rarefractions
300
Sound travels the fastest through which medium?
Solid, liquid or Gas
Solid
300
The part of the electromagnetic wave that can be seen
Visible light
300
An object that lets all light pass through
Transparent
300
When light rays come to the same point
Converge
300
What is C?
Incidence Ray
300
The cells at the back of the eye that converts the light into signals
Retina
400
How fast the soundwave repeats itself
Frequency
400
Objects move when their natural frequency is played
Resonance
400
The longer the wavelength, the slower the frequency
True or False?
True
400
A green glass lets yellow light pass through
True or False?
False
400
When light rays spread apart
Diverge
400
What is B?
Reflected Ray
400
Which part of the eye refracts the light as it enters the eyes?
Lens and Cornea
500
The distance the particles vibrate
Amplitude
500
Can we hear in space?
No, because there are no particles to pass the vibrations through
500
All parts of the electromagnetic wave can be seen by the eye
True or False?
False
500
The colour of the object that we see is the light reflected off it
True or False?
True
500
Is the following a convex or concave lense?
Convex lense
500
Are the "angle of reflection" and "angle of incidence" will always be the same?
Yes, they will always be
500
How is light refracted inside the eye?
Converge or Diverge?
Converge
