Question

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?
