​Refraction and Lenses

2. Calculate the refractive index of a medium where the speed of light in that medium is

   a. 4,5 x 10⁵ m/s

   b. 6 x 10⁷ m/s

3. If an object is 8 cm away from a convex lens of focal length 20 cm, determine the location of the image and the linear magnification

4. If an object is 16 cm away from a concave lens of focal length 4 cm, determine the location of the image

5. If image is 12 cm away from a convex lens of focal length 3 cm, determine the image's height if object's height is 4,5 cm.
