WebJan 9, 2024 · Incoherent light is the opposite of this. The photons of incoherent light oscillate at different frequencies, and their wave lengths are not in phase with each other. … WebUse the incandescent light (just a regular lightbulb). You can start with the light source about 20 cm from one end. Then hold your rectangular opening right next to the opening of the incandescent source. The screen can go about 20 cm past the opening. (Leave the laser in place, even though you won't be using it yet.)

Can Natural Sunlight Induce Coherent Exciton Dynamics?
