(5 points) using the relation find (λ, t) using the planck formula for blackbody radiation energy density u(v, t) given on lecture. show that the maximum of the radiation energy density u(λ, t) is inversely proportional to the temperature amaxt determine the numerical value of constant b. this is usually called wien displacement law.

What is the difference between electrically neutral objects and electrically charged objects

Uppose we consider the system of the three capacitors as a single "equivalent" capacitor. given the charges of the three individual capacitors calculated in the previous part, find the total charge qtot for this equivalent capacitor. express your answer in terms of v and c.

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
