Waves Flashcards
1
Q
Mechanical Waves
A
Wave that travels through a medium (material which waves pass)
2
Q
Transverse Waves
A
Wave which disturbance perpendicular to direction waves travels
3
Q
Longitudinal Waves
A
Wave which disturbance parallel to direction wave travels
4
Q
Wave Properties
Amplitude
A
- Symbol: A
- Def: how far wave moves from starting position
- Controlled by energy
Ex: 1. Ocean - height of wave 2. Sound - loudness
5
Q
Wave Properties
Wavelength
A
- Symbol: upside down y
- Def: length of wave (one spot to same spot)
- Controlled by frequency
Ex. 1. Ocean - distance between waves 2. Sound - diff pitches
6
Q
Wave Properties
Frequency
A
- Symbol: f
- Def: how often wave passes certain point
- Controlled by wavelength
Ex. 1. Ocean - how fast waves are 2. Sound - pitch
7
Q
Wave Interactions
Reflection
A
- Bouncing of wave off surface
- All waves reflect
8
Q
Wave Interactions
Absorption
A
- Transfer of energy by wave to medium
- Factors: 1. Type of wave 2. Type of material
9
Q
Wave Interactions
Transmission
A
- Passage of wave through medium
10
Q
Wave Interactions
Diffraction
A
- Bending of waves when goes through a gap in a barrier
