A helium-neon laser provides coherent red light (wavelength < 1 μm); the dimensions of the apertures or obstacles that we place in the laser beam are correspondingly small.
A white sheet of paper attached with magnets to a screen mounted on one side panel of a lab bench.
Laser set up at the other end of the bench so that it points at the paper.
Laser is switched on.
What would be the size of the laser beam spot (reasonable estimate)?
A piece of silk is placed in the laser beam (close to the laser and perpendicular to the beam).
What would be the pattern of the transmitted light on the screen?
Could this be a shadow pattern of the threads in the cloth?
Silk is rotated about the beam axis- what happens?
Silk stretched slightly in one direction- what happens?
Silk is removed.
Laser beam reflected beam at a glancing angle from the grooves in a piece of a phonograph record. Beam is reflected from a spot where the grooves are running nearly parallel to the beam.
The piece of record is rotated back and forth around the axis of the beam.
Beam is then reflected from a spot where the grooves are running perpendicular to the beam.
What happens as you vary the angle of incidence of the beam until the beam is traveling almost parallel to the surface of the record?
