What is occurring when a light wave diffracts?

question 5 options:

a.the light wave is bending around an obstacle or through a barrier.

b.the light wave is bouncing off of a smooth surface.

c.the light was is absorbing.

d.the light wave is bending when it goes from gas to liquid.

The light wave is bending around an obstacle or through a barrier shows diffraction.

Explanation :

Light is one of the forms of energy. It enables us to see objects clearly. It shows many phenomena like the reflection of light, refraction, interference, diffraction etc.

The light rays bend when it passes through a narrow opening or obstacles. The essential condition for the diffraction is that the size of an obstacle should be comparable to the wavelength of light.    

Hence, the correct option is (a) " The light wave is bending around an obstacle or through a barrier".

I believe the answer is: Prices for goods and services increased, and a dollar bought less than it previously had

In the 1970s, united states was experiencing a period of economic stagnation which later known as called the great inflation of the 1970s.

During this period, the number of unemployment skyrocketed and the value of our currency fall dramatically, which caused an increase in overall products and less amount of products it can obtain with previously same amount.
