The distance between two atoms in a crystal is 0.2 nm. Diffraction would be ideal (specular reflection occurring,as pictured in my extra notes slides for Bragg's Law) if the wavelength of the interfering wave was the same as the distance between obstacles that cause the scattering.
Calculate what speed a neutron would need to have to be suitable for this task ,to have a de Broglie wavelength equal to the distance between the two atoms.
Television sets sometimes use a rabbit ears antenna to the right. A rabbit-ears antenna consists of a pair of metal rods. The length of each rod can be adjusted to one quarter of the wavelength of an electromagnetic wave whos frequency is 125 Mhz...
question short sections of two very long parallel lines of charge are shown fixed in place and separated by l 10.0 cm.
Glycerine in water diffuses along a horizontal column that has a cross-sectional area of 2.0 cm2. The concentration gradient is 3.2 10-2 kg/m4, and the diffusion rate is found to be 5.9 10-15 kg/s. Determine the diffusion coefficient.
Two strips of brass, each 4.00 cm wide and 55.0 cm long, are placed with their endsoverlapping by 1.00 cm. The overlapping ends are then rivetedtogether by four rivets, each with diameter 0.500 cm.

You have 33 tuning forks that oscillate at close but different frequencies. What are the (a) maximum and (b) minimum number of different beat frequencies you can produce by sounding the forks 2 at a time, depending on how the frequencies differ?
Your groceries are in a bag with paper handles. Find what is the greatest mass of groceries that can be lifted safely with this bag, given that the bag is raised with constant speed
The rms current in an RL circuit is 0.28 A when it is connected to an ac generator with a frequency of 60.0 Hz and an rms voltage of 25 V. (a) Given that the inductor has an inductance of 170 mH, what is the resistance of the resistor? ? (b) Find the..
