1. A _________________ _________ causes light rays from a distant source to converge to a _____________ ______________ 2. Charging by induction, a charged rod is brought near a neutral conductor: the electrons in the conductor redistribute such that there is a net positive charge away from the rod (T/F) 3. Electrical resistivity doesn’t change when temperature changes (T/F) 4. With a magnetic core, the total magnetic field is increased by a factor of 10^3 to 10^4 relative to the field...

(a) Light from distant objects, such as stars, are imaged by a single lens. Assuming the focal length of the lens is 10 cm and the aperture size is 2 cm, what is the minimum resolvable angle? Write every step. (b) The same lens is used for imaging an amplitude grating. What is the minimum grating spacing that will yield any intensity variation(s) on the image plane using (i) coherent and (ii) incoherent illumination? Be very specific in your answer...

The Earth's magnetic field protects us from cosmic rays, which are extremely-high-energy subatomic particles generated by esoteric processes in interesting parts of the universe. To get an idea of how this protection might happen, pretend the earth's magnetic field has a constant value of 5.0 x 10^-5 T (northward) from the ground up to a height of 50 km. (a) Suppose a high-energy proton (charge +1.6 x 10^-19 C, mass 1.67 x 10^-27 kg) hits the top of the earths...
