PHYS-232 Heat and Waves - Homework 2 Winter Semester 2008 Due on Thursday, January 31, 2008 1. Along the direction of propagation of a sinusoidal wave there lie two points A and B that separated by 2 cm. The phase of the wave at point B is π/ 6 behind the phase at A. If the frequency of the source of the wave is 10 Hz, what are the wavelength and wave speed ? 2. Solve problem 2.2.1 of the class notes. 3. Solve problem 2.3.2 of the class notes. 4. A string of length L is fixed at both ends.

Unformatted text preview: T . Suppose the density of the string is ρ . Find out at what frequency this string can vibrate. 5. There are two sound waves coming from two diﬀerent sources. The ﬁrst one has a frequency of 400 Hz and the second one has a frequency of 1200 Hz . The wave amplitude of the ﬁrst one is twice of that of the second one. Find out the ratio of the intensity of the ﬁrst wave to the second one 1...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
