Whats a device that changes electrical energy into light energy?
An LED (light-emitting diode) is a common device that converts electrical energy into light energy. When an electric current is passed through the LED, it emits light.
Does the volume of a solid expand when its area expands?
If its due to temperature rise, essentially all the molocules move further apart from each other in whats known as volumetric expansion, so when its volume increases, so does its surface area.

Whats the difference between thick and thin lens?
A thick lens has varying thickness across its surface, which affects how light is refracted. A thin lens is assumed to have a uniform thickness, simplifying calculations in optics. Thick lenses can produce more complex optical effects compared to thin lenses.
