Physics
1 answer:

Answer:

  • 514.27 ( wavelength )

the color is green

  • 602.93 nm  ( orange color )

the observation is that there is a change of visible color

Explanation:

A) wavelength of visible light that is most strongly reflected from a point on a soap

refraction n = 1.33

wall thickness (t) = 290 nm

2nt = (2m +1 ) ∝/2 -----equation 1

note when m = 0

therefore ∝ =  4nt/ 1 = 4 * 1.33 * 290 = 1542.8nm we will discard this

when m = 1

equation 1 becomes

∝ = 4nt/3 =( 4 * 1.33 * 290) /  3 = 1542.8 / 3 = 514.27 ( wavelength )

the color is green

B) the wavelength when the wall thickness is 340 nm

∝ = 4nt / 2m +1

where m = 1

∝ = (4 * 1.33 * 340 ) / 3  = 1808.8 / 3 = 602.93 nm  ( orange color )

the observation is that there is a change of visible color

Earth's orbit around the Sun is slightly elliptical. Thus, Earth actually gets closer to the Sun during part of the year. What h
Fudgin [204]

Answer:

C)Earth's orbital speed is greater when it is closer to the Sun than when it is farther from the Sun.

Explanation:

We can use Kepler's 2nd law or the law of area to answer this question.

The law states that the rate of area swept out by a planet's orbit is same throughout the orbit. For the farthest point since the distance is large as compared to to the nearest point, the possibility that area swept is large. Hence, to compensate the extra swept area. the orbital speed has to decrease  at the largest point.

Hence, planet's speed is greater when it is closer to sun than the speed when it is farther.

1 1.1.2 Quiz: The Nature of Physics
Natasha2012 [34]

Answer: Theory (D.)

Explanation:

A theory is based on years of careful scientific study, observation, and experimentation.

On the other hand, a law describes a phenomena without explaining it. An observation is merely a documentation of a phenomena and may or may not be explained. An experiment is a procedure done to test the effect of a specific variable, but does not necessarily explain WHY something occurs.
