Prob. 2. Two converging lenses, A witha focallength of +2.0cm and B
with a focal length of +5.0cm, areplaced 14cmapart. An object is
place 3.0cm to the left of lensA.
A) Use graphical methods, to scale, toconstruct theray diagram
with a measurement of the final imageposition andheight; and
B) Use the lens equation determinethecharacteristics of the
image.
Prob. 3. A prism with angles 45°,45°, and 90° is tobe used to turn a
beam of light through a 90° angle.What is theminimum index of
refraction for the material of theprism that willgive the total
internal reflectionneeded?
Prob. 4. A tarantula is sitting 4.5min front of aconcave spherical mirror
with radius of R =1.4m.
A) Construct a ray diagram to scaleshowing theobject, image and
the mirror. Determine graphicallythecharacteristics of the image.
B) If the image is 5.0cm tall, howhigh is thetarantula?
Prob. 5. A Young’s double slitapparatus has theslit separation of
0.12mm and the distance between theslits and theviewing
screen is 55 cm.
A) If monochromatic light ofwavelength λ = 550x10-9mpasses
through the slits, calculate thedistance betweenthe central
(bright) fringe and the adjacentbright fringe.
B) Now imagine that you are usingX-rays, λ=1x10–9minstead of
visible light in this experiment. Whatwould theslit separation
need to be in order to have thedistance betweenthese first two
bright fringes be1cm?
Prob. 6. Acombination of blue light (n=1.60) andred light (n=1.50)is
incident on the surface of a flatglass plate.Because of dispersion
there are two refracted rays. Draw adiagram showingthe incident
and both refracted rays, indicatingthe red and theblue rays.
Calculate the angle between therefracted blue andred rays.
