Answer:
<h3>What is the angular speed of the earth around the sun? </h3>
It takes the Earth approximately 23 hours, 56 minutes and 4.09 seconds to make one complete revolution (360 degrees). This length of time is known as a sidereal day. The Earth rotates at a moderate angular velocity of
<h3>
What is the tangential speed of the earth? </h3>
The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second--or roughly 1,000 miles per hour.

Explanation:
Answer: D. Diffract
Explanation:
Diffraction is a phenomenon that is based on the deviation of the waves (light waves in this case) when encountering an obstacle.
In addition, it is important to note this phenomenom occurs in all types of waves (ncluding electromagnetic waves).
So, in a general way:
Diffraction happens when a wave (mechanical or electromagnetic wave) meets an obstacle or a slit . When this occurs, the wave bends around the corners of the obstacle or passes through the opening of the slit that acts as an obstacle.
Hence, the correct option is D:
<h3>In order to demonstrate the interference of light waves, the light source emits rays of light, which <u>diffract</u> towards the double slit.</h3>
