Combining light from multiple light sources
The lights emitted from several light sources merge and do not "interfere" with each other. If, for example, two identical lamps illuminate the paper from the same distance, we see the paper twice as bright.
Explain why, in such an experiment, the three beams do not converge on the flashlight, as they did when using a single LED lamp in the previous experiment.
What image would we see if we placed three slits in the light of three LED lamps. Make a drawing and put on it the rays of light that are important for explaining the result of the experiment.
Kui tõstame taskulambi ühele küljele ning sõelume ühe piluga katses vertikaalselt paigutatud kolme LED-lambi valgust, siis näeme paberil vaid ühte kiirt. Selgita tekkinud nähtust.
