Flashcards in Topic 8: Spectroscopy, Video C: Wave Properties Deck (11):
1

Light is scientifically known as what? 

Electromagnetic radiation (EM).

2

What is a wavelength?

The distance between 2 consecutive troughs or peaks in a wave.

3

What is frequency?

Number of waves that pass a given point per second.

4

Frequency (cycles per second) is measured in what unit?

Hertz.

5

What is amplitude?

Amplitude is the height of the wave as defined by a trough or a peak.

6

The brightness of light is related to what aspect of it's wave.

Amplitude.

7

True or false. Wavelength and frequency are inversely proportional.

True.

8

Wavelength times frequency equals what?

c, the speed of light. (3 x 108 m/s)

9

The wavelength of a light defines it's what?

It's color.

10

Blue light has a shorter wavelength than red light or red light has a shorter wavelength than blue light?

Blue light has a shorter wavelength than red light.

11

What is the equation for wavelength and frequency?

c=(lambda)(v)

v=frequency

Lambda=wavelength (in meters)

c=speed of light (3 x 10^8)
