Answer 1

The particles in the air vibrate in the direction the wave goes .

Question 2

Infrasound

Answer 2

Is a sound that is below the range of human hearing .

Question 3

Ultrasound

Answer 3

Any sound above human hearing range

Question 4

Resonance

Answer 4

Is when a object vibrates so much that it causes the object to vibrate as well.

Question 5

Intensity

Answer 5

Describes the rate at which a sound wave transmits energy through a given area of the medium .

Question 6

Decibel

Answer 6

Is a unit rate of which sound is measured by.

Question 7

Fundamental frequency

Answer 7

When a frequency of a wave is also the frequency of the vibrations .

Question 8

Harmonics

Answer 8

When something vibrates at its fundamental frequency and at certain whole number multiples of that frequency .

Question 9

Sonar

Answer 9

Determines distance by measuring the time it takes for sound waves to be reflected back to the source .

Question 10

Basilar membrane

Answer 10

Long flexible membrane that is in the cochlea

Question 11

Photon

Answer 11

A unit or quantum of light .

Question 12

Intensity

Answer 12

Measures the amount of light illuminating or measures how intense the light is .

Question 13

Radar

Answer 13

A system that uses reflected radio waves to determine velocity and location of objects .

Question 14

Electromagnetic spectrum

Answer 14

Consist of light at all possible energies frequencies and wavelengths

Question 15

Light Ray

Answer 15

A light Ray is a imaginary line that goes in the same direction that the light travels .

Question 16

What is a virtual image

Answer 16

Is a image that you see from a apparent path of light rays .

Question 17

What is a real image ?

Answer 17

A real image is a result from when light rays are focused into one specific point .

Question 18

Diffused reflection

Answer 18

Is the reflection of light when the incident ray is reflected .

Question 19

What is a lens ?

Answer 19

Are transparent material that refracts light waves to make them converge or diverge to create a image .

Question 20

What is magnification ?

Answer 20

It is a change in size compared to the object .

Question 21

What is a prism ?

Answer 21

They separate white light from different colors .

Question 22

What is dispersion

Answer 22

Is what separates colors from other colors in light waves .

Question 23

What is mirage ?

Answer 23

Is when you look at a road on a hot day and see water on the road that is reflected from the atmosphere to the road .

Question 24

What is a converging lens?

Answer 24

A converging lens bends light inward .

Question 25

What is focal point ?

Answer 25

Is when light rays are pointed in one small area .

Question 26

What is geometrical optics ?

Answer 26

It behaves like a ray would .

Question 27

What is angle of reflection?

Answer 27

Light rays that deflect off of an object

Question 28

Angle of incidence ?

Answer 28

Are light rays striking an object

Question 29

What is law of reflection ?

Answer 29

Angle of reflection and the angle of incidence .

Question 30

What is normal ?

Answer 30

Normal is a line in the middle of a perpendicular object .

Question 31

What is a convex mirror

Answer 31

A convex mirror are mirrors that make the image bulge out .

Question 32

What is a concave mirror ?

Answer 32

A concave mirror is a mirror that makes the image appear to be indented .

Question 33

What is internal reflection?

Answer 33

Internal reflection is when the angle of incidence is striking somethings boundary .
