Calculate the speed of light in an unknown substance whose index of refraction is 1.65. Would you expect the light to bend towar

(a) The speed of light in the unknown substance is determined 1.82 x 10⁸ m/s.

(b) The light will bend away from the normal since speed of light in air is not equal to speed of light in the substance.

<h3>What is the speed of light?</h3>

The speed of light passing from air into the substance is calculated as follows;

refractive index = speed of light in air / speed of light in the substance

speed of light in the substance = speed of light in air/refractive index

speed of light in the substance = (3 x 10⁸) / (1.65)

speed of light in the substance = 1.82 x 10⁸ m/s

Thus, the light will bend away from the normal since speed of light in air is not equal to speed of light in the substance.

When an electron moves from a lower energy level to a higher energy level, the atom:
Ede4ka [16]

Answer:

A. absorbs light

Explanation:

For an electron to move from a lower energy level to a higher energy level, energy needs to be added to the atom.

In most cases this required energy will be light: The electron of the atom will absorb the energy of the light and move to a higher energy level.

When said electron comes back to the lower energy level, the atom will conversely give off light.

How do you decide whether a sample of matter is a solid,liquid,or gas?
prohojiy [21]
As solid is a hard surface and it can be changed to any shape although it is placed to any container whereas liquid can be poured from one container to another and gases have less bulk so they are not exaggerated by gravity

Which of the following laws is NOT explained by Dalton's atomic theory? A.the law of conservation of mass B. the periodic law C.
zysi [14]

B. the periodic law

Explanation:

The periodic law was not explained by the Dalton's atomic theory.

The periodic law was first postulated by Dimitry Mendeleef and Lothar Meyer around 1869 where they independently arrived at the periodic table or chart.

  • The table was based on the periodic law which states that "chemical properties of elements are a periodic function of their atomic weights".
  • The modern periodic law was restated by Henry Moseley in the early 1900s. He changed the basis of the law to atomic number.
  • The present periodic law is stated as "the properties of elements are a periodic function of their atomic number".

The laws of conservation of mass, multiple proportions and definite proportions are all explained by the Dalton's atomic theory.
