Ray of laser start from the air and collide with the middle side of some matter > How many total internal reflections done in this matter ??
n ( matter)= 1.48
n (air)= 1.00
The length of matter = 42.0 cm
The width of matter = 3.1 mm
Ray of laser collide by angle =20(degree)

  • Physics - ,

    Draw the figure. Next, determine the critical angle. Now start to use a geometrical plot to trace the ray. At each side interaction, determine the angle: below critical or not, determine.
