Question # 05 Photons are sometimes represented by pictures like this. Just what is this a picture of? Explain what this "graph" shows. Question # 06 Electron 1 is accelerated from rest through a potential difference of 100 V. Electron 2 is accelerated from rest through a potential difference of 200 V. Afterward, which electron has the larger de Broglie wavelength? Explain. Question # 07 Double-slit interference of electrons occurs because: i. The electrons passing through the two slits repel each other. ii. Electrons collide with each other behind the slits. iii. Electrons collide with the edges of the slits. iv. Each electron goes through both slits. v. The energy of the electrons is quantized. vi. Only certain wavelengths of the electrons fit through the slits. Which of these (perhaps more than one) are correct? Explain.
