Slide 56

Evaluation: State Standards

Waves carry energy from one place to another

Identify transverse and longitudinal waves in mechanical media such as spring, ropes, and the earth (seismic waves)

Solve problems involving wavelength, frequency, & speed.

.

Slide 57

EVALUATION: State Standards

Radio waves, light, and x-rays are different wavelength bands in the spectrum of electromagnetic waves whose speed in vacuum is approximately 3x10 m/sec

Sound is a longitudinal wave whose speed depends on the properties of the medium in which it propagates.

Slide 58

EVALUATION: State Standards

Identify the characteristic properties of waves:

Interference

Diffraction

Refraction

Doppler Effect

Polarization.
