How hot is the sun through a magnifying glass?
It can reach 900 degrees Celsius. The thermal power output is greatly dependent on the CR, structural and material properties. 500 degree is not a difficult task to achieve by either a magnifying glass (lens), a Fresnel lens or a parabolic mirror.
Can you burn things with a magnifying glass without the sun?
The double convex lens in the magnifying glass focuses the beam of heat rays at one single point. Concentrating the energy at a single point causing a flammable object to set fire. Can you make magnifying glass fire without sun? Sure, you can absolutely use laser light to create fire without sun.
Can a magnifying glass start a fire?
A magnifying glass starts a fire through the use of heat from the sun. This is done by positioning the glass so that the sun’s rays pass through the lens, forming a small point of light on a pile of dry kindling.

Why does a magnifying glass burn?
When a magnifying glass is held over a piece of paper at a distance equal to its focal length, the sun’s rays falling on the lens converge at a point that lies somewhere on the paper. Thus, solar energy spread over the lens’ surface area gets concentrated at one point. That’s when the paper starts burning.
Can you really burn ants with a magnifying glass?
Burning ants with a magnifying glass is an acceptable act as a child but torturing animals in childhood is a sign of mental illness. Seriously, animal abuse is in NO WAY acceptable.
