Q. A spherical mirror is polished on both sides. When used as a convex mirror, magnification is +1/4. What is the magnification when used as a concave mirror, the object left over the same distance from the mirror? Give your answer to three significant figures.
Q. At which wavelengths (or energies) will you observe lines in infrared absorption (a phonon absorbs a photon) and raman scattering spectra? The temperature is 300 k. raman scattering is excited with a cw Argon laser at 514.5 nm
