You can start fire by focusing the sunlight using the magnifying glass. I searched the web whether you can do the same using moonlight. The only thing we want is to gather enough energy in a sufficiently small volume with oxygen and some fuel to light a fire; hence most of the energy for the...The plane mirror neither converges nor diverges the Ray of light , it simply reflects all the rays of light falling So overall conclusion is , no other mirror can be more effective for efficient functioning of a solar cooker A concave mirror is used in a solar cooker as it uses heat of the sunlight to cook food.The light that enters the space between the mirrors do have an angle of attack, and will therfor be reflected in a zig-zag path untill the light exits on the other side. so if only a ew percent of the light get absorbe diwth each bounce there will be practically clsoe to nothing left prettymuch instantly.This is our page for asking and answering questions for Harry Potter: Hogwarts Mystery.

Other solutions right here don't take into accout two essential aspects. First, the heated point radiates too. Second, superb lens with large diameter to focal period ratio don't exist. The latter can be proved with entropy.

Suppose the "magical" lighting fixtures (which might comprise the perfect lens) machine exists clear of Earth. Suppose additionally we encompass the program with a radiation tub of cast angle \pi$ with temperature $T_0$. Then, due to the second law of thermodynamics, the gadget will be in equilibrium, when the temperature in the "magical" software is uniformly also $T_0$. Then, as to simulate some radiating object (equivalent to Moon), we remove most of the radiation, and leave only a small percentage of the forged angle. Of path, if the "magical" lighting fixtures device consists only of lens and mirrors, the radiation towards the heated point can only decrease $\Rightarrow$ it is temperature $T \leq T_0$. Note that the temperature $T$ only depends on the ability it's heated, now not on the spectrum of radiation.

If arbitrarily huge diameter to focal length lens existed, these may be used to focal point light of a radiating body (corresponding to Sun or Moon) to arbitrary intensities, giving upward push to arbitrarily high temperatures (contradicting the proof).

Thus if the heated level is black, the utmost intensity of the black-body radiation is the depth of the reflected light. Thus the maximum temperature might indeed be in the range of [scrape_url:1]

If the heated level isn't black, but radiates simplest very high-frequency spectrum, the achievable temperatures would be higher, almost definitely temperatures up to the temperature of the sun.
