Answer:
Depth,
Explanation:
It is given that,
Absorption coefficient,
Surface reflectivity, T = 0.1
Energy of light, E = 3 eV
We need to find the depth at which half the incident optical power has been absorbed in the material. The relationship between the absorption coefficient and intensity of light is given by :
Since, the incident power is becoming half. So,
Since, ln (0.5) = -0.693
x = 0.0000173 m
or
So, the depth at which half the incident optical power has been absorbed in the material is . Hence, this is the required solution.
It will be radiation since the microwave uses a lot of heat waves to heat up the popcorn
The correct answer is high temperature. Fusion occurs on the sun where the temperature is high and it can happen. There is no way to have the necessary amount of high energy on earth that can enable fusion and usable energy to occur because of the way things on earth work.
