Quick True or False Questions?

1. Light energy can be emitted in a continuous spectrum.


2. Matter waves indicate that all matter has a wave property.


3. The Compton effect shows that momentum is conserved in a photoelectric effect.


4. In the photoelectric effect, the brighter the light, the faster the ejected electrons will move.





Any help is appreciated.Quick True or False Questions?
i think you'll find 1. is actually true!! Have you never heard of ';absorption spectra'; where you see a WHOLE SPECTRUM OF LIGHT apart from a few lines that have been absorbed by gases. So where does that spectrum come from huh?





2. True


3. True





4. False, energy (speed) of the emitted electron depends on the energy of the incident photon, which is determined by its frequency. Brightness is determined by the number of photons per second.Quick True or False Questions?
1.False


2.True


3.False


4.True
1. True


2. True


3. True


4. False
-False
