3. A laser light is held at a height of 30cm above the surface of a block of glass, and forming an angle of 30 with such surface, as in Figure. The block of glass has a depth of 15cm. The laser is right above the edge of the block. The light is hitting the bottom surface of the glass at a distance of 63em from the edge of the glass block. (a) Caleulate the index of refraction of the glass. (b) Caleulate the total time it takes light to complete the trip from the laser to the bottom surface of the block. The same material is now used to mamafacture a comverging lens with spherical surfaces of equal radius. (e) Caleulate the radius of the curvature such that the resulting lens has a focal length of 50cm. A pencil of length 10cm is held at a distance of 60 cm from that lens. (d) Caleulate the size and position of the resulting image, highlighting whether it is real or virtual, erect or inverted. Include a drawing depicting all focal points, and rays you used to find the position and size of the image.

3. A laser light is held at a height of 30 cm above the surface of a block of glass, and
forming an angle of 30° with such surface, as in Figure. The block of glass has a
depth of 15 cm. The laser is right above the edge of the block. The light is hitting the
bottom surface of the glass at a distance of 63 cm from the edge of the glass block.
(a) Calculate the index of refraction of the glass.
(b) Calculate the total time it takes light to complete the trip from the laser to the
bottom surface of the block.
The same material is now used to manufacture a converging lens with spherical surfaces
of equal radius.
(c) Calculate the radius of the curvature such that the resulting lens has a focal
length of 50 em.
A pencil of length 10cm is hekd at a distance of 60 cm from that lens.
(d) Calculate the size and position of the resulting image, highlighting whether it is
real or virtual, erect or inverted. Include a drawing depicting all focal points,
and rays you used to find the position and size of the image.
BONUS:
Calculate the magnification of this lens.
