Radio waves are diffracted by large objects such as buildings, whereas light is not noticeably diffracted by large objects such as buildings. Why is this?

Choose one answer.
a. Radio waves are unpolarized, whereas light is plane polarized.
b. The wavelength of light is much smaller than the wavelength of radio waves.
c. Light is coherent and radio waves are usually not coherent.
d. Radio waves are coherent and light is usually not coherent.

Expert Solution

b. The wavelength of light is much smaller than the wavelength of radio waves
As the visible light have smaller wavelength they need small gap for defraction.

(1) Radio waves and light are electromagnetic waves and transverse waves that can operate in a medium or in space. What is an Aether or ether? Upon which medium does sound travel the fastest? (2) Some scientists think that ether does exist but does exist in another dimension that we cannot see. Can you elaborate on this?
