I know it’s not real and virtual. I don’t think it’s real so I’m thinking it’s just virtual but I’m not sure.
a.) Draw a simple version of the human eye looking at the sun (never look at the sun yourself!), showing the lens and the retina. Label s, s’, and f. b.) If the distance between the lens and the retina is around 2 cm, relabel s, s’, and f with their exact distances. c.) Why do we need a lens in the eye to view distant objects?
A 10.5 cm diameter spot of light appears on a screen 1.2 m behind a circular opening that is 2.4 m away from a point light source. a. What is the diameter of the opening, in cm? b. What action(s) would cause a larger spot of light appear on the screen? (can be more than one) - Moving the screen closer to the opening - Making the opening larger - Moveing the light source closer to the opening c.
