Warm up

1
Warm up

• At 0C sound travels through air at a speed of
  330 m/s. If a sound wave is produced with a
  wavelength of 0.10 m, what is the waves
  frequency? 

2
Reflection

• Waves that bounce off a smooth surface

3
Diffraction

• Waves passing through a small opening or around a
  corner

4
def Resonance

• The increase in the amplitude of vibration that
  occurs when external vibrations match the objects
  frequency

5
Polarization

• Light is allowed to pass only in one direction if
  it passes through a polarizing filter

6
def Refraction

• The bending of light as the light passes into a
  new medium

7
def Interference

• The interaction between waves that meet

8
Electrical

• Carried by moving charges in a conductor

9
Magnetic

• Related to motion due to the attraction or
  repulsion of magnets

10
Nuclear

• Associated with bonds holding the nuclei of atoms
  together

11
Sound

• Created by disturbances that causes waves

12
Heat

• Kinetic energy of particles moving from high to
  low temperatures

13
Light

• Energy moving in electromagnetic waves

14
Mechanical

• The sum of kinetic and potential energies of
  moving objects

15
Chemical

• Related to forces between the bonds of atoms

Exit Question

• One tuning fork is struck and placed next to an
  identical fork. The two forks do not touch. The
  second tuning fork starts to vibrate because of
   
• F interference
• G the Doppler effect
• H resonance
• J standing waves
