Desk Lamp
What are the differences between sunlight and a desk lamp shining on clear saran wrap?
I'm doing a science project and need an in-text citation. If anyone can find one that states the differences please help me.
No bulb emits the full spectrum of electromagnetic radiation like the sun does since no bulb is powered by fusion at its core. Nor does a bulb produce the luminosity of the sun. Bulbs emit in very narrow ranges primarily from the visible spectrum. Incandescent bulbs emit high in the red and beyond into the invisible infrared range explaining why they become so warm.
Light, spectrum and luminosity
