A 90-watt red light bulb and a 60-watt green light bulb are turned on. Which bulb emits photons with the greater energy? Compare a lightbulb that emits mostly red light with a total power of 100 W to a lightbulb that emits mostl...
(a) A 20% efficient 5-watt LED light emits 540 nm light. Calculate the number of photons it emits per second. Also, find the speed to which a free electron would be accelerated if it absorbed one of these photons. (b) A proton has a wavelength of 3 cm. Ho ...
Laser light is basically a monochromatic, coherent and directional electromagnetic radiation (Renk, 2017). The laser used in PIV has a high energy density and a precise pulse control, attributes that reinforce its advantages over ordinary light. Most solid-state laser sources used in PIV systems ...
