Question

I'm not entirely sure my answers are correct. Please give me some guidance lol

Press the large red "button" on the laser pointer to turn it on. When placing the mouse on the small brass-colored knob on the end of the laser pointer allows you to rotate the laser source. Rotate it until it is pointing upwards and to the right at a 30° angle. Move the prism such that the incident ray hits the bottom left side, about one-sixth of the way up from the bottom left corner. 06 - Of 30 - - - Ó 30 09 60 -06 1. Using the protractor in the simulation, measure each of the angles and record below: Angle of incidence at first interface, 0,1 = 30° Angle of refraction at first interface, OR1 = 30° 2. Use Snell's law to find the index of refraction for the glass prism (index of refraction for air: n = 1.0.) ni sin 011 n2 sin R1 n2 = -1

Answer 1

30 air n = 1 glass nz Angle of incidence at first interface On1 = 30° Angle of refraction at first interface ( since one division is equal to 5 degrees therefore PRI = 5 x 4 Pri = 20 From Snell's law n sinn = nesinori n2 nisin 1 sinori (1) (sin30) n2 = (sin 20 ) n2 = 1.46 Index of refraction for glass prism is 1.46
