Physics Quiz: Small Scale Fading And Multipath

What is the reflection of waves?

• Refraction

• Diffraction

• Reflection

• Absorption

How does the Doppler effect affect the frequency of a wave?

• The frequency of a wave is only affected by the amplitude of the wave

• The frequency of a wave is affected by the relative motion between the source of the wave and the observer.

• The frequency of a wave is only affected by the medium through which it travels

• The Doppler effect has no impact on the frequency of a wave

Explain Rayleigh fading.

• It is a phenomenon related to solar flares

• It is a statistical model for the effect of a propagation environment on a radio signal.

• It is a result of signal reflection

• It is a type of fading caused by clouds

Describe Rician fading.

• A type of fruit that is known for its sweet taste and juicy texture.

• The process of a material losing its strength and breaking apart over time.

• A mathematical equation used to calculate the area of a circle.

• A radio propagation model that predicts the power of a radio signal in a multipath environment.

How do waves reflect off surfaces?

• The angle of incidence is greater than the angle of reflection

• The angle of incidence is less than the angle of reflection

• According to the law of reflection, the angle of incidence is equal to the angle of reflection.

• The angle of incidence has no effect on the angle of reflection
