In a room with a spherical ceiling light, Kofi and Priya are standing on opposite sides of the room. Both are facing each other. An opaque ball is suspended from the ceiling right in front of Priya, blocking her view of the light. Taking into consideration the positioning of the light, Kofi, Priya, and the opaque ball, what happens to the light Kofi sees when Priya moves to her right?
Respond very briefly.
When Priya moves to her right, she no longer blocks the light coming from the ceiling light straight towards Kofi. As a result, the opaque ball will begin to cast a shadow in the direction opposite to where the light is, which is towards Priya's new position. Therefore, the shadow of the ball will move to Priya's right as she does, and more light will be visible to Kofi since Priya is no longer obstructing his view of the light. Kofi will see increased illumination from the light as the blockage (Priya) has moved out of his line of sight with respect to the light's direct path.
