Question

Hello, everyone. I calculated my answers for my Physics homework but I wanted someone to help me double-check my answers and work to verify my answers before I submit all of them.

Whoever can successfully answer all 6 problems and provide their answers will receive 1,500 Chegg points as immediately as possible. Judging by the agility of your responsiveness, I will even consider adding more points into this question.

I value your time and effort and if you visit this link here is proof that I do in fact award points to users, even if they get a few problems incorrectly.

Thank you very much in advance and have a wonderful day!

Explanation / Answer

1)

cB/cA = nA/nB

==> cB = 1.44 * 1.5e8 = 2.16 x 10^-8 m/s

----------------------------------------------------------------------------------------------------------

2)

a)

44 degrees

b)

n1 sin(theta1) = n2 sin(theta2)

1* sin(44) = 1.33 * sin(theta2)

==> theta2 = 31.5 degrees

----------------------------------------------------------------------------------------------------------

3)

tehtai = arctan(x/y) = arctan(7/2.9) = 67.496

n1 sin(thetai) = n2 sin(thetar)

==> 1 * sin(67.496) = 1.33 sin(thetar)

==> thetar = 44 degrees

==> x' = 4 * tan(thetar) = 4 * tan(67.496) = 3.86 m

==> d = x + x' = 10.9 m

----------------------------------------------------------------------------------------------------------

4)

d1 = t/tan(90 - theta1) = 6.06/ tan(90-30.9) = 3.62684 mm

n1 sin(30.9) = n2 sin(theta2)

==> theta2 = 19.746

d2 = t tan(theta2) = 6.06 * tan(19.746) = 2.1753 mm

d = d1 - d2 = 3.62684 - 2.1753 = 1.45154

D = d sin(90-theta1) = 1.45154 * sin(90-30.9) = 1.25 mm

----------------------------------------------------------------------------------------------------------

5)

a)

1/f = 1/p + 1/q

==> 1/q = 1/f - 1/p = 1/112 - 1/118

==> q = 2202.67 mm

==> q = 2.20 m

b)

M = 2202.67/118 = 18.667

==> 27 * 18.667 = 504 mm

==> 34 * 18.667 = 635 mm

----------------------------------------------------------------------------------------------------------

6)

f = 1/D = 1/65.30 = 0.015314

1/p = 1/f - 1/q = 1/0.015314 - 1/1.539e-2

==> p = 3.10 m

h' = q/p * h = 1.539e-2/3.1011 * 5.3 = 0.0263 cm
