PHY3063 Spring 2007 Problem Set 3 Department of Physics Page 1 of 1 PHY 3063 Problem Set #3 Due Thursday February 8 (in class) (Total Points = 50, Late homework = 50%) Reading: Finish reading Tipler & Llewellyn Chapter 2 and start reading Chapter 3. Problem 1 (10 points): The mass and radius of the sun are given by M sun = 1.99×10 30 kg , R sun = 6.96×10 8 m and the mass and radius of the earth by M earch = 5.98×10 24 kg , R earth = 6.37×10 6 m and the distance between the sun and the earth is d = 1.5×10 11 m . What is the fractional shift in the wavelength of the light coming from the sun to the earth due to the gravitational red shift? Express your answer in terms of the wavelength at earth minus the wavelength emitted at the sun all divided by the emitted wavelength ( i.e. (earth-sun)/sun). Assume that the earth and sun are at rest and that there are no other massive objects in the solar system. Problem 2 (20 points): The mass of the sun is M sun = 1.99×10 30 kg and the radius of the earth is R earth = 6.37×10 6 m . The distance between the sun and the earth is d = 1.5×10

### 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.
