CP Physics Chapter 15 Refraction and Lenses
Refraction of Light • Change of velocity • Change of wavelength
Example #3 How fast does light travel through diamond?
Change in direction
Fig 35 -13, p. 1104
Example #4 What is the angle of refraction of a light ray entering water from air at an angle of 30 degrees?
Example #5 At what angle does the light ray exit into the flint glass? 38° water ethanol flint glass
Example #6 How far are you (1. 8 m tall) standing from the edge of a pool, if you see a fish under water? The fish is actually 0. 9 m deep and 0. 5 m from the edge of the pool. Assume that the pool is completely filled. B. What is the apparent depth of the fish?
Example #7 What is the refracted angle of a light ray going from diamond at 37 -deg into air?
Critical Angle and T. I. R.
Fiber Optics
Example #8 What is the critical angle of a ray going from diamond into air?
Mirages
Rainbows
Formation of Rainbows
Why is the sky blue during midday and reddish/orange at sunset or sunrise?
Convex Lens (Converging Lens) F F
Focal Point of a Convex Lens
Spherical Aberration Fig 36 -34, p. 1152
Chromatic Aberration Fig 36 -35, p. 1153
Example #6 What is the focal length of a convex lens if an image is located 4. 5 cm in back of the lens and the object is placed at the same location but in front of the lens? what is the magnification of the lens?
Example #7 A magnifying glass is used to magnify the image of an insect that is placed 3 cm in front of the lens with a radius of curvature of 10 cm. Where is the image located?
Concave Lens (Diverging Lens)
Example #8 Where is the image located if an object is placed 5 cm in front of a 6 cm concave lens? What is the magnification of the lens? If the image is 1. 1 cm tall, what is the size of the object?
Example #9 The magnification of a particular lens is to magnify an object by +3. 5 times its original size. If the object is placed 4 cm in front of the lens, where is the image located and the focal length of the lens?
Example #10 A lens is used to magnify an image by 0. 4 times. If the image is RSU and the focal length is 5 cm, A) where must the image and object be placed? B) How far apart are the image and object?
