CH301 Fall 2009 Worksheet 2 1. Calculate wavelength from the following frequencies. a) 625 kHz b) 734 MHz c) 8.4 E14 Hz d) 92 GHz 2. Given the following energies, calculate the frequencies of the photons. a) 17 kJ b) 564 E-25 J c) 98 pJ d) 230 J 3. Rank the wavelengths of the photons in question 2 from longest to shortest. Use A, B, C, or D to identify the photon. (Hint: No calculations necessary.) 4. The double slit experiment is a famous demonstration of the wave nature of light: when light of a single frequency is passed through two parallel sits in a barrier, it produces an interference pattern on a surface placed on the other side. Draw an example of an interference pattern (as amplitude of light received vs. position). Compare the frequency and phase of the light waves coming from the two slits at the dark spots and at the light spots on the interference pattern. 5. When passed passed through very fine gratings (or even regular crystals), electrons and neutrons form a distinctive pattern of ridges and troughs because of their wave nature. What
