Magazine Problem 9
Why is it much more difficult to see interference fringes for light reflected from a thick piece of glass than from a thin film? Would it be easier if monochromatic light were used?
Problem 9
Calculate the wavelength of light that has its third minimum at an angle of \(30.0^{\circ}\) when falling on double slits separated by \(3.00 \mu \mathrm{m}\). Explicitly, show how you follow the steps in Problem-Solving Strategies for Wave Optics.
Problem 9
The angle between the axes of two polarizing filters is \(45.0^{\circ}\). By how much does the second filter reduce the intensity of the light coming through the first?
Problem 9
You are told not to shoot until you see the whites of their eyes. If the eyes are separated by \(6.5 \mathrm{~cm}\) and the diameter of your pupil is \(5.0 \mathrm{~mm}\), at what distance can you resolve the two eyes using light of wavelength \(555 \mathrm{~nm} ?\)
Problem 9
Find the frequency of a tuning fork that takes \(2.50 \times 10^{-3} \mathrm{s}\) to complete one oscillation.
Problem 10
Find the frequency of a tuning fork that takes \(2.50 \times 10^{-3} \mathrm{s}\) to complete one oscillation.
Problem 10
What is the wavelength of light falling on double slits separated by \(2.00 \mu \mathrm{m}\) if the third-order maximum is at an angle of \(60.0^{\circ} ?\)
Problem 10
How many lines per centimeter are there on a diffraction grating that gives a first-order maximum for \(470-\mathrm{nm}\) blue light at an angle of \(25.0^{\circ} ?\)
Problem 10
If you have completely polarized light of intensity \(150 \mathrm{~W} / \mathrm{m}^{2}\), what will its intensity be after passing through a polarizing filter with its axis at an \(89.0^{\circ}\) angle to the light's polarization direction?
Problem 10
(a) Find the angle between the first minima for the two sodium vapor lines, which have wavelengths of \(589.1\) and \(589.6\) \(\mathrm{nm}\), when they fall upon a single slit of width \(2.00 \mu \mathrm{m}\). (b) What is the distance between these minima if the diffraction pattern falls on a screen \(1.00 \mathrm{~m}\) from the slit? (c) Discuss the ease or difficulty of measuring such a distance.
