Transcript of PH 223 22:1-3

A double slit is illuminated simultaneously with orange light 600 nm and an unknown light.
The m=4 fringe of the unknown wavelength overlaps the m=3 fringe of the orange light. What is the unknown wavelength
A double slit interference patten is created by two narrow slits spaced 0.20 mm apart. The distance between the first and the fifth minimum on a screen 60 cm behind the slits is 6.0 mm. What is the wavelength (in nm) of the light used?
500 nm
Light of wavelength 600 nm illuminates a diffraction grating. The second order maximum is at 39.5 degrees. how many lines per millimeter does this grating have?
A diffraction grating with 500 line/mm
is illuminated by a 633 nm laser light.
what is the maximum number of bright fringes that can be seen?

7
"Does Young's experiment only work with one wavelength of light?"
"Does light act more like a wave, or more like a ray?"
"Do the wave, Ray Model, and Photon model compliment each other in any way?"
"Could we get an overview of the photon model and how it differs from the other two."
