When white light is incident on a prism, which one of the resulting color components will have the lowest index of refraction? A. Green B. Yellow C. Orange D. Blue

Answers

Answer 1

Answer: The correct answer is C. Refractive index is dependent on the wavelength this is seen in the Cauchy equation. The refractive index decreases with increasing wavelength and since orange has the highest wavelength among the choices given thus it will have the least refractive index.

Which characteristics do all terrestrial planets have? Select all that apply.A. Water
B. Iron core
C. Rocky crust
D. Thin atmosphere
E. Dense atmosphere
F. Relatively high density

Answers

"Terrestrial" means 'on Earth' or 'like Earth'.

The so-called 'terrestrial planets' are Mercury, Venus, Earth, and Mars.
The asteroid belt separates them from the 4 gas-giant planets, in a wide
gap where there should be another planet but there isn't.

Among the terrestrial planets as a group:

A). Water
   No. Only earth has water (now).

B). Iron core
   Yes. Most probably all.

C). Rocky crust
   Yes. All.

D). Thin atmosphere.
E). Dense Atmosphere.
   No.
   Only Venus has a dense one.
   Mercury probably has none.
   Earth has the Goldilocks atmosphere.

F). Relatively high density.
   Yes.
   True of all the terrestrial planets.
   Earth is the most dense of all the planets.

White light is shining on a green grape. The grape _____.absorbs green light
reflects green light
reflects all colors of light except green
transmits green light

Answers

The grape absorbs all colors except green, and green light is the
only light that remains to bounce around and enter people's eyes.

This is a big part of the reason why, whenever somebody looks at
the grape, they remark "Oh look ! The grape is green !"

Answer:

reflects green light.

Using a hammer to drive a nail, it is the reaction force that brings the motion of the hammer to a stop but the _______________ that drives the nail into the wood.

Answers

The correct answer for the question that is being presented above is this one: "action force." Using a hammer to drive a nail, it is the reaction force that brings the motion of the hammer to a stop but the action force that drives the nail into the wood.

Explanation:

The reaction force is what presents you drive because it acts on you. Newton's Third Law of Motion describes that forces perpetually come in action-reaction pairs. The Third Law states that for every action force, there is an identical and opposite reaction force. The ball exerts an equal and opposite force on the bat.

The blue end of the visible color spectrum has wavelengths, and the red end has wavelengths.

Answers

Answer: Blue end has shorter wavelength and red end has longer wavelengths.

Explanation:

Visible region consists of Violet, Indigo, Blue, Green, Yellow, Orange and Red. These colors are arranged in the order of increasing wavelengths which means that blue region has shorter wavelength and as we move towards red region, the wavelength of light increases.

Blue region has shorter wavelength and higher frequency whereas red region has longer wavelength and smaller frequency.

Frequency and wavelength follow inverse relation.

$\nu\propto (1)/(\lambda)$

Answer: Blue end has shorter wavelength and red end has longer wavelengths.

During Mr. Nye's science class, students were expected to identify various substances using physical properties they could easily measure. Mr. Nye gave each of the five groups a green, metal cube. The students had to identify what metal the cube was made of. The length of each side was 3.0 cm and the mass was 270 grams. What property should Mr. Nye's science students use to identify the metal in the cubes?

A) color

B) density

C) mass

D) volume

Answers

Density is the best property to use, as while multiple different metals could create cubes with the same color, mass, or volume, no different metal could create a cube with the same mass and volume. Density is based on mass and volume, and as a result no two different metals will have the same density.

Hey there

The students should use density.

Why voltmeter and resistence are parallel in ohm's law.

Answers

Never mind Ohm's Law. A voltmeter measures the difference in electrical potential
between two points. So if you want to measure the difference in electrical potential
between two points, you touch one probe of the meter to each point, and somehow
the internal guts of the meter are able to sense the difference in electrical potential
between the two points.

If the two points have non-reactive impedance (a resistance) between them, then the
difference in electrical potential between the two points, as indicated by the meter,
will be close to (resistance between the two points) x (current flowing between them).
