Question

I need help with these particular questions on optics. Also if you would please work them out

A equilateral prism (all three angles are 60.0 degree) is shown here, sitting on a horizontal surface. Its index of refraction is 1.60. A laser initially running parallel to the horizontal is incident on the left side of the prism. After the laser line goes through the prism and reaches it on the other side: Does the laser refract or reflect? What is the final angle of the laser with respect to the horizontal table (answer this whether it refracts or reflects)

Answer 1

4. An object (arrow) is placed at a position p away from a thin converging lens. Use a ruler and a ray-trace diagram on this page to determine the answers to questions a-d on the next page (you will use calculations to answer e). Remember to use the three principle rays: the Focal-Parallel Ray, the Central Ray, and the Parallel-Focal Ray Object Image

answers

(a) see rays diagram

(b) from the rays diagram M = -1.5

(c) real

(d) inverted

(e)

$\frac{1}{p}+\frac{1}{q}=\frac{1}{f} \Rightarrow \frac{1}{22cm}+\frac{1}{q}=\frac{1}{14cm}$

$q=38.5cm$

so:

$M = -\frac{q}{p} = -\frac{38.5cm}{22cm}$

$\boxed{M=-1.75}$  exceeding the value from rays diagram in 16%.
