A researcher measures the thickness of a layer of benzene (nn = 1.50) floating on water by shining monochromatic light onto the film and varying the wavelength of the light. She finds that light of wavelength 525 nmnm is reflected most strongly from the film. What does she calculate for the minimum thickness of the film?

8.75e-8m

Explanation:

The thickness of the film for the constrctive interference is represented as : 2t = ( m + 0.5 ) λ*

Where λ* is the new wavelength and it is represented as

λ* = λ÷μ

The minimum thickness of the film is represented as t*. At m = 0

2tmin = ( 0 + 0.5 ) × ( 525e-9 )/1.50

2tmin = 0 + 262.5e-9/1.50

2tmin × 1.50 = 2.625e-7

3tmin = 2.625e-7

tmin = ( 2.625e-7 ) ÷ 3

tmin = 0.875e-7

tmin = 8.75e-8m

jupiter

explanation:

it is so massive and has such a strong gravitational pull its likely prevented the formation of a planet between itself and mars in the asteroid belt

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
