From Young's experiment, how does the frequency of light affect the number of lines observed?
Marina CMI [18]

Answer : (C) "Higher frequencies have larger spaces between lines".

Explanation:

In Young's experiment, the condition for constructive interference is given by :

dsin\theta=n\lambda.........(1)

n is order or number of lines observed

d is distance between slits

\theta is the angle between the path and the line from screen to the slits.

We also know that, c=\nu \lambda

or

\lambda=\dfrac{c}{\nu}

where,

c is the speed of light

\nu is frequency

\lambda is wavelength

So, equation (1) turns into

dsin\theta=n\dfrac{c}{\nu}

\nu=\dfrac{n\ c}{d\ sin\theta}

So,

\nu\propto n

or

Higher frequencies have larger spaces between line.

So, correct option is (C).

Describe the shapes and relative energies of the SPD &amp; f atomic orbitals
Deffense [45]

Explanation:

The shapes and relative energies of the orbitals s,p,d and f orbitals are given by the principal quantum number and the azimuthal quantum number.

The principal quantum number gives the main energy level and the azimuthal quantum number denotes the shape of the orbitals.

  • For the principal quantum number, they represent the energy levels in which the orbital is located or the average distance of the orbital from the nucleus. It takes the number n = 1,2,3,4,5,6,7......
  • The azimuthal quantum number(L) shows the shape of the orbitals in subshells accommodating electrons. The number of possible shapes is limited by the the principal quantum number.

Which one of the following represents an acceptable set of quantum numbers for an electron in an atom? (arranged as n, 1, m, and
babymother [125]

Answer:

The correct option is A) 3, 2, -2, -1/2.

Explanation:

Quantum numbers represent different properties regarding the level, sublevel and orbital in which an electron is. There are 4 quantum numbers:

  1. Principal quantum number (<em>n</em>): indicates the level of energy and gives information about the size of an orbital. It can only take positive and integer values, e. g., 1, 2, 3...
  2. Angular quantum number (<em>l</em>): indicates the sublevel of energy and provides information about the shape of the orbital. Some common shapes are spherical (<em>l</em>=0) and polar(<em>l</em>=1). Shapes for bigger l are more complicated. <em>l</em> values depend on <em>n</em> values. <em>l</em> values can be integers up to (<em>n</em>-1). For example. if <em>n</em> = 2, <em>l</em> can take the values 0 and 1.
  3. Magnetic quantum number (<em>m</em>): it gives information about the orientation in space of an orbital. It may take any integer value between -l and +l. For example, if <em>l</em> = 1, <em>m</em> can take values -1, 0 and 1, each one referring to an orbital p along a different axis in the space (x, y and z axes).
  4. Spin quantum number (<em>ms</em>): it refers to the spin angular momentum of an electron and it can take 2 values:  -1/2 or +1/2.

A) 3, 2, -2, -1/2 is correct because it follows every rule.

B) 3, 3,-4, 1/2 is wrong because if <em>n</em>=3, <em>l</em> can only be up to 2, and l from -3 to +3.

C) 3,2,0,0 is wrong because <em>ms</em> cannot take the value 0.

D) 3,3,3, -1/2 is wrong because if <em>n</em>=3, <em>l</em> can only be up to 2.

E) 3, 4, 6, -1/2 is wrong because if <em>n</em>=3, <em>l</em> can only be up to 2, and <em>l</em> from -3 to +3.
