What is Light? Maxwell and the Electromagnetic Spectrum

How to Calculate the Wavelength of a Wave When Wave Speed and Frequency are Known

Two electromagnetic waves are represented below. 
(i) <img src="" alt="" />
(ii) <img src="" alt="" />
(a) Which wave has the greater intensity?

Correctly done including conversion of g to kg.

The deBroglie equation is used to calculate the velocity once the mass is converted to kg.

 The de Broglie relation relates a mass to wavelength. 

At what speed must a 145-g baseball travel to have a wavelength of 1.15 &#215; 10&#x2212;34 m?

Single electrons interfere with themselves.

This is correct along with another choice.

The wave nature of the electron is exhibited only when electrons are passed through a slit.

There are other manifestations of the wave nature of an electron.

The wave nature of an electron prevents electrons from crashing into the nucleus as predicted by classical mechanics.

Both the first and second statements are correct.

The wave nature of an electron is manifested in a number of ways.

Both the first and third statements are correct.

Both the second and third statements are correct.

Which of the following statements is/are true concerning electrons?

Wave Period and Frequency

Consider the two waves shown here, which we will consider
to represent two electromagnetic radiations:
(a) What is the wavelength of wave A?

Wavelength&nbsp;is the distance from one crest of a wave to another, whereas frequency is the number of waves within a second.&nbsp;

Quantum Numbers: Spin Quantum Number

The Spin Quantum Number deals with the spin of an electron within an orbital.

Speed of Light

The Speed of Light in a vacuum is related to the wavelength and frequency of a light particle.

Bohr Equation

In the Bohr Equation, the energy and wavelength a photon is related to its energy shell transitions.

Quantum Numbers: Angular Momentum Quantum Number

The&nbsp;Angular Momentum Quantum Number&nbsp;gives the shape of the atomic orbitals.

Emission Spectrum

Emission Spectra is a series of lines formed when emitted light is focused by a slit and passed through a prism. &nbsp;

Introduction to Quantum Mechanics

The 4 Quantum Numbers provide us the coordinates to find the theoretical location of an electron.

Quantum Numbers: Nodes

A node is the region in an atom with zero electron density and where an electron is least likely to exist.

The Energy of Light

The Energy of Light&nbsp;involves the use of a new variable Planck's Constant.

Electromagnetic Spectrum

The Electromagnetic Spectrum is the different forms of radioactive energy that exists in our universe.

Heisenberg Uncertainty Principle

Heisenberg's Uncertainty Principle&nbsp;tries to explain the potential duality of an electron behaving as either a particle or wave.&nbsp;

Quantum Numbers: Number of Electrons

The Quantum Numbers can give both the quantity and location of electrons within a given atom.&nbsp;

Quantum Numbers: Principal Quantum Number

The Principal Quantum Number gives both the size and energy of an electron shell.&nbsp;

Photoelectric Effect

What happens when light strikes the surface of a metal? The Photoelectric Effect&nbsp;can help to explain that.&nbsp;

Quantum Numbers: Magnetic Quantum Number

The Magnetic Quantum Number gives the location of an electron within a specific orbital.

Bohr Model

In the Bohr Model, electrons can move up and down to different orbitals or shells based on absorbing or releasing of energy.&nbsp;

De Broglie Wavelength

The&nbsp;De Broglie Wavelength equation relates wavelength to velocity or speed.&nbsp;
