Double-slit interference: In a two-slit experiment, the slit separation is 3.00 × 10-5 m. The interference pattern is recorded on a flat screen-like detector that is 2.00 m away from the slits. If the seventh bright fringe on the detector is 10.0 cm away from the central fringe, what is the wavelength of the light passing through the slits?

Double-slit interference: Coherent monochromatic light of wavelength 632.8 nm passes through a pair of thin parallel slits. The figure shows the central portion of the pattern of bright fringes viewed on a screen 1.40 m beyond the slits. What is the distance between the two slits?

Diffraction grating: What is the angular separation of the two second-order spectral lines having wavelengths 417 nm and 388 nm using a diffraction grating having 456 lines/mm?

Single-slit diffraction: A single slit forms a diffraction pattern, with the first minimum at an angle of 40.0° from central maximum, using monochromatic light of  490-nm wavelength. What is the width of the slit?

Double-slit interference: Light of wavelength 575 nm passes through a double-slit and the third order bright fringe is seen at an angle of 6.5° away from the central fringe.  What is the separation between the double slits?

Field intensity: A sinusoidal electromagnetic wave in vacuum delivers energy at an average rate of 4.00 µW/m2.  What are the amplitudes of the electric and magnetic fields of this wave? (c = 3.0 × 108 m/s, μ0 = 4π × 10-7 T ∙ m/A, ε0 = 8.85 × 10-12 C2/N ∙ m2) (10 points)

Diffraction grating: A diffraction grating has 300 lines per mm. If light of wavelength 630 nm is sent through this grating, what is the highest order maximum that will appear?

Diffraction grating: A He-Ne laser, which produces light of wavelength 632.8 nm, is used to calibrate a diffraction grating.  If the first-order maximum occurs at 20.5° from the central spot, what is the distance between the slits of the grating?

Double-slit interference: Light from a monochromatic source shines through a double slit onto a screen 5.00 m away. The slits are 0.180 mm apart. The dark bands on the screen are measured to be 1.70 cm apart. What is the wavelength of the incident light?
