What do seismic, water, and light waves have

Energy

1

How to waves transfer energy when they interact with matter

Energy causes particles to vibrate and collide with one another causing a chain reaction; particles go back to their original position

2

Particle motion in transverse and longitudinal waves

Perpendicular equals transverse
parallel equals longitudinal

3

Wave parts on transverse wave

Amplitude, crest, trough, wavelength, rest position

4

Parts on longitudinal wave

Compression, rarefaction, wavelength

5

Describe the relationship between wavelength energy and frequency

Wavelength down frequency up energy up

Wavelength up frequency down energy down

LLL longer lower less

6

Equation for wavelength frequency and wave speed

Velocity (meters per second) = frequency (hertz) x wavelength (meters)

7

Explain the cause of electromagnetic waves

Electromagnetic waves result when a charge particle is accelerated or decelerated

EM waves are created by the vibration of the electric charge

8

What are the seven parts of the electromagnetic spectrum

Radio, micro, infrared, visible, ultraviolet, x-rays, and gamma

9

Compare the seven parts of the electromagnetic Spectrum according to wavelength and energy

Radio long wavelength low-frequency low-energy

Gamma short wavelength high-frequency high-energy

10

What is reflection and example

Incoming light hits an object bounces off equal and opposite angle

Mirror reflects light

11

Refraction

When light waves change direction as they pass through medium

Straw appears to break in water

12

Diffraction

Bending, spreading of waves on obstacle

Rainbow

13

Absorption

Photons from light hit atoms and molecules, vibration occurs

Tanning

14

Scattering

Light bounces off object in different direction

Sky is blue

15

Transmission

Light goes through transparent medium, doesn't change

Window

16

Constructive interference

Crest overlaps crest, trough overlaps trough, amp increase

17

Destructive interference

Crest overlaps trough and amp decreases

18

Doppler effect

As sound approaches you waves compress, wavelength appears to decrease, frequency increases, pitch increase. When sound moves away waves spread apart, wavelength increases, frequency decreases, and pitch decreases
