Answer:
The critical angle for light is 41.81 degrees.
Explanation:
We have, light is propagating from a material with index of refraction of 1.50 to a material with index of refraction of 1. It is required to find the critical angle for light. It is angle for which the angle of refraction is equal to 90 degrees. It is given by :
So, the critical angle for light is 41.81 degrees.
Our Sun is one of many stars in the Milky Way galaxy. Earth is closer to the Sun than any other star. This is evident because " we rely on the Sun's radiant energy on Earth".
<u>Option: B</u>
<u>Explanation:</u>
The Sun produces much radiant energy which is distributed as light to the Earth. Plants supports only process called photosynthesis for their food production, transform the electromagnetic energy in sunlight into chemical energy for their food. Radiant electromagnetic waves can be either visible or invisible.
Maximum solar radiation is absorbed by the atmosphere, but much of what hits the surface of the earth is emitted back into the atmosphere for heat energy to result. Dark colored items like asphalt consume radiant energy more easily than objects colored with light.
