Electromagnetic Waves (5/13)

Question 1

Characteristics of electromagnetic waves

Answer 1

Mathematically can be described as waves
Mathematically can be described as particles
They can carry energy
They travel slower in water than in a vacuum

Question 2

Light waves

Answer 2

electromagnetic waves

Question 3

Transverse waves

Answer 3

Electromagnetic waves that oscillate perpendicularly to the direction of the wave’s propagation

Question 4

Electric and magnetic components are…

Answer 4

Perpendicular to each other and perpendicular to velocity

Question 5

Electromagnetic radiation

Answer 5

multiple electromagnetic waves

Question 6

Circular polarization

Answer 6

polarization where the direction of the electric and magnetic fields rotate steadily over time. can be right handed or left handed (clockwise or counterclockwise)

Question 7

Electromagnetic spectrum

Answer 7

Low WL/high v/high frequency-»

gamma rays, x-rays, UV, VIBGYOR, IR, microwave, FM radio, AM radio, long radio waves High WL/low v

Question 8

Visible light spectrum

Answer 8

400-750 nm

violet-red

Question 9

Spectrometry

Answer 9

used to measure the degree to which a substance absorbs different wavelengths of EM radiation
The color of light we see is caused by the wavelength of light that are reflected back, so NOT absorbed

Question 10

Speed of electromagnetic waves in a vacuum (c)

Answer 10

3 x 10^8 m/s

Question 11

Master wave equation

Answer 11

velocity=wavelength x f
velocity=c (only in a vacuum)
wavelength and frequency are inversely related

Question 12

Energy of waves

Answer 12

E=h x f

h= 6.62 x 10^-34 m^2*kg/s

Question 13

Relationship between E=h x f and c= lambda x f

Answer 13

E=hc/lambda
