Homework Answers
the resistivity of copper vary 1.6 *10-8 ohm*m to 1.72 *10-8 ohm*m
ni - si alloy it varies a lot. I can't say. I will encourage you to look up it within your manual for theoretical value and calculate. because resistivity depends on temp and many other factors.

Examine the % differences between the experiment values and
theoretical value of speed of sound. By using which frequency do
you reach smaller % difference with the theoretical value?

Below is an image from a double slit experiment obtained by shining a laser through one. I used a He-Ne Laser, wavelength = 632.8 nm, and shined through two slits whose separation distance is d = 0.250 mm. The light was shined upon a sheet of paper taped to the wall and was 10.0 ft 4.00 inches away from the double slit. I circled the bright spots (constructive interference) and identified the central maximum (m = 0). I saved the...
