Fluorescence

A
  • Energy of the UV light that is absorbed by the phosphor, which emits visible light.
  • This visible light that is emitted is called fluorescence.

Q

Electromagnetic Spectrum

A
  • The entire range of electromagnetic waves from low to high frequency.
  • Made up of RADRO, MICROWAVE, INFRARED, VISIBLE SPECTRUM, ULTRAVIOLET, X-RAYS, GAMMA RAYS.

Q

Concave Mirror

A
  • Mirror whose reflecting surface curves inward
17
Q

Principal axis

A
  • The thick, horizontal normal that touches the center of the mirror
  • Helps locate the positions of objects that are placed in front of the mirror
18
Q

Focal Point

A
  • The focal point of a lens is generally noted by the capital letter “F.” This is the point in space where the light rays will converge to after passing through a converging lens.
19
Q

Focal Length

A
  • The distance from the center of the lens to the focal point.
20
Q

Principal Axis

A
  • The principal axis is a horizontal imaginary line drawn through the center of the lens.
21
Q

Real Image

A
  • Image that is formed when reflected rays meet
22
Q

Convex Mirror

A
  • Mirror whose reflecting surface curves outward
23
Q

Refracted ray

A
  • Ray that is bent upon entering a second medium
24
Q

Angle of refractuib

A
  • The angle between the normal and a refracted ray
25
Q

Index of refraction

A

The ratio of the speed of light in a vacuum to the speed of light in a given medium

26
Q

Critical angle

A

angle of incidence that produces and angel of refraction of 90 degrees.

27
Q

Frequency

A

The number of crests of a wave that move past a given point in a given unit of time.

Most common unit of frequency is the hertz (Hz), corresponding to one crest per second.

Frequency of a wave can be calculated by dividing the speed of the wave by the wavelength.

28
Q

Speed of light

A

???

29
Q

Lens

A

A clear curved piece of glass or plastic that is used in eyeglasses, cameras, telescopes, etc., to make things look clearer, smaller, or bigger

30
Q

Laser

A

A laser is a special source of light of only one pure color (or WAVELENGTH). You can’t break up laser light into other colors.

31
Q

Magnification

A

?

32
Q

4 characteristics of an image in a plane mirror

A
  • Image is the same size as the object
  • The same distance from the mirror as the object
  • The same orientation as the object
  • The image is a virtual Image
