Answer:
wide is the aperture is 7.5 cm
Explanation:
Given data
aperture away = 2.00 m
wide bright = 15 cm = 0.15 m
screen behind the aperture = 2.00 m
to find out
How wide is the aperture
solution
we know here we have a triangle shape that height will be
2 + 2 = 4 m and base 0.15 m
so we now easy find w by triangle
w / 2 = 0.15 / 4
so w = 0.15 / 4 × 2
so w = 0.075 m
wide is the aperture is 7.5 cm
