Green laser light with a wavelength of 650 nm travels towards a photodetector.

a.How long does it take the laser to reach the photodetector located 50 meters away?

b.What is the change in the arrival time of the light if a 1 meter block of lucite is placed along the path for the laser to travel through? (index of refraction = 1.50)

c.What is the speed of light through the lucite?

Next, take a second laser (red) with wavelength of 720 nm and also place it 50 meters from the photodetector.

d.You machine a new block of lucite such that when the red light passes through the block, it arrives at the photodetector at the exact same time as the green light traveling through the 1 meter block in part b. Is the lucite block for the red light longer or shorter than the 1 meter lucite block used for the green laser light?

e.What is the speed of the red laser through the lucite?

f.What is the length of the lucite for the red light?

Green light of wavelength 500 nm passes through a diffraction grating having 10−610−6 m between lines.   How far away from the central bright spot is the next bright spot on a screen 2 m away (in meters)? Suppose the light passing through the diffraction grating is composed of many different wavelengths. Rank the following colors according to the spacing between the bright spots of that color from least to greatest, so the least would have the smallest spacing between maxima....

In Young's double-slit experiment, 632.8 nm light from a HeNe laser passes through the two slits and is projected on a screen. As expected, a central maximum (constructive interference) is observed at the center point on the screen. Now, a very thin piece of plastic with an index of refraction n=1.48 covers one of the the slits such that the center point on the screen, instead of being a maximum, is dark. Part A Determine the minimum thickness of the...

1) 2 point charges are separated by a distance of 8 cm. The left charge is 48 mC and the right charge is -16mC. Using a full sheet of paper: draw the 2 charges separated by 8cm, centered in the sheet. (if you are missing a ruler estimate 8cm as ⅓ a paper sheet length). [6] a) Draw field lines to indicate the electric fields for this distribution. [4] b) Draw 3 equipotential surfaces, 1 each, that pass: -Through the...
