Answer:
0.48 kW
Explanation:
Given;
Efficiency of solar panel = 0.15
Total power input of the solar panel = 3.2kW
The useful power output of the solar panel is the amount of power transmitted by the solar panel for use. It can be expressed as a function of its efficiency and total power input.
Useful power output = efficiency × Total power input
Substituting the given values;
Useful power output = 0.15 × 3.2 kW = 0.48 kW

-- pass the light through a lens
The path of the light is bent (refracted) to a new direction.

-- pass the light through a prism
The light is spread out according to the different wavelengths
that may be in it.
-- put something black in the light's path
The light is completely absorbed and is never seen again.
