Question 5 of 15 Incorrect Incorrect Map A sapling learning As you may have learned when studying the properties of thermal energy, building contractors often install double-glazed windows to prevent thermai energy ("heat") from entering/exiting the building. Although effective as insulators, such windows present interesting optical effects. air gap. If the light encounters the glass at an angle of 40.000 with respect to the glass, find the shift in path Ax as the light enters the room. (Use na 1.00) 40.000 Number 14.00 mm 32.0 mm glass 25.6 mm air glass 32.0 mm There is a hint available! View the hint by clicking on the bottom divider bar.

Explanation / Answer

from air to glass

sin(90-40)*na = sinr1*ng

sin50*1 = sinr1*1.4

r1 = 33.17

dx1 = sin40*t1/cos33.17

t1 = 32 mm

dx1 = 24.57 mm

from glass to air the refracted ray is parallel to incident
ray.so, there is no deviation

from air to glass

from air to glass

sin(90-40)*na = sinr2*ng

sin50*1 = sinr2*1.4

r2 = 33.17

dx2 = sin40*t1/cos33.17

t2 = 32 mm

dx2 = 24.57 mm

d = dx1 + dx2 = 49.14 mm <--------answer
