White light passes through sodium vapor and is then analyzed with a prism. The resulting spectrum

A)

is continuous.

B)

consists of spectral lines.

C)

is continuous and contains absorption lines.

D)

none of the above.

a) Light with a wavelength of 600 nm is incident on a single slit whose width is 0.01 mm. The screen is 80 cm from the slit. Calculate the distance between the first-order minimum and the centre.

b) Monochromatic light with a frequency of 5.50x1014 Hz is directed through a diffraction grating ruled with 6.00x103 lines/m. What is the distance between the third bright band and the fifth dark band of the interference pattern formed on a screen 2.50 m from the grating?

Monochromatic light of wavelength λ1 is sent through two closely-spaced slits separated by a distance d1 = 1.8 mm. A resulting interference pattern is shown on a screen L1 away. Another monochromatic light source, this one of wavelength λ2, is sent through a diffraction grating toward the same screen, resulting in a second interference pattern. The diffraction grating is a distance L2 from the screen and has 400 lines per mm etched onto it. A) Assume that L1 = L2...

1. A diffraction grating is used to separate the spectral lines of light, emanating from a gas discharge tube (e.g., a neon light), that is normally incident on the grating. On a screen placed 2.0 m from the grating, the third-order (m = 3) interference maximum for violet light (λ = 4.4 × 10−7 m) is found to be 0.20 cm farther from the location of the central maximum (m = 0) on the screen than the second-order maximum of...
