RADIO
MICRO
INFARED
VISIBLE
ULTRAVIOLET
X-RAY
GAMMA

2

What are the 6 parts of EMC

Reflection
Refraction
Diffraction
Absorption
Scattering
Transmission

3

What is reflection

Incoming light hit object, equal and opposite

Mirror

4

Refraction

When light waves change direction as it passes through a medium

Separating colors on a prism

5

Diffraction

Bending or separating of waves

Spectrometer rainbow

6

Absorption

Photons from incident hit molecules, vibration occurs

Skin and sun

7

Scattering

Light bounces off object in different directions

Sky blue

8

Transmission

Light goes through transparent medium, doesn't change

Window

9

Constructive and destructive interference

C- crest overlaps crest; trough overlaps trough, amp increase

D- crest overlaps trough, amp descreases

10

Doppler effect

Sound approaches: waves compress, wl appears to decrease, f increases, p increases

Sound moves away: waves spread apart, wl increases, f decreases, p decrease
