Question1

A guitar string is 90 long and has the mass of 3.4. The distance from a bridge to the support post is, and string is under a tension of 520.

What are frequencies of the fundamental and first two overtones?

Question2

Yellow light of wavelength 583 nm is used to view the object under a microscope. The objective lens diameter is 8.55 mm.

(a.) What is a limiting angle of resolution?

(b.)Assume it is possible to use visible light of any wavelength. What colour have to choose to give the smallest possible angle of resolution, and what is the angle?

(c.)Assume water fills the space between an object and an objective lens. What result does this change have on the resolving power as 583 nm light is used?

Question3

The particles in nucleus of an atom are approximately 1.00×10^−15 m apart, even as the electrons in an atom are about 1.00×10^−10 m from nucleus.

Compute an electrical repulsion between two protons in a nucleus if they are 1.50×10−15 apart.
