3. If the distance of the screen is moved from 100. cm to 200. cm the area of light would in-crease from 150. cm^2 to
A. 37.5 cm2
B. 75 cm2
C. 300 cm2
D. 600 cm24.

Light is projected onto a screen 75.0 cm from a light source. The light sensor records a reading of 4,436 lux at this distance. If the screen is moved from 75.0 cm to 150. cm, the light sensor reading would change to
A. 17,700 lux
B. 8,870 lux
C. 2,218 lux
D. 1,110 lux

5. If you use a screen in the last problem and tilt it the light reading would go down, this is be-cause.
A. In science when we tilt things they always get lower
B. As we tilt the screen the area of light increases and spreads the light over a lager area.
C. As we tilt the serene the area of light decreases and makes the light more concentrated.
