What is Spectrum?

Spectrum:

A series of coloured bands separated and arranger in an order of their respective wavelengths. (or) A spectrum is a group of wavelengths.
Example: Visible Spectrum (VIBGYOR)

VIBGYOR

V - Violet, I- Indigo, B- Blue, G - Green, Y - Yellow, O - Orange, R - Red

Intensity:

The amount of force or energy of heat, light, sound etc.

Visible Spectrum:

The range of wavelengths covering red colour to violet colour is called the visible spectrum.
Red colour      -  High wavelength,    Low frequency
Violet Colour  -  Low Wavelength,    High frequency

Wave: 

A regularly repeated disturbance or displacement in a medium like air, water.

Wave nature of light:

Electromagnetic waves are produced when an electric charge vibrates (moves back and forth).
for example, Visible light
Visible light is an electromagnetic wave and the speed of light (c) is 3 x108 m.s-

What is the electromagnetic spectrum?

Electromagnetic spectrum:

The entire range of electromagnetic wave frequencies is known as the electromagnetic spectrum.
The entire range of electromagnetic wave wavelengths is also known as the electromagnetic spectrum.

Characteristics of an electromagnetic wave:

The electromagnetic wave can be characterised by its wavelength and frequency.

Wavelength:

The wavelength of a wave is the distance from one wave peak to the next.
The distance between any two consecutive wave peaks is called the wavelength.

Frequency:

The frequency (v) of a wave is the number of wave peaks that pass by a given point per unit time.

Home Task:

Read the following questions. You can write the answers in the comment section along with your name.
  1. What are the three subatomic particles?
  2. What is the speed of light in Vaccum?
  3. Define the electromagnetic spectrum.

Main Postulates of Bohr's Model of a Hydrogen Atom: The following are the main postulates of the Neils Bohr's Atomic model of a Hydrogen atom, Electrons in an atom occupy stationary orbits (energy levels) of fixed energy at different distances from the center called the nucleus. When an electron jumps from a lower energy state to a higher energy state, it absorbs energy and emits energy when such a jump occurs from a higher energy level (state) to lower energy level (state). The energy of an electron in an atom can have only certain values E1, E2, E3,... i.e. the energy is quantized. The states corresponding to these energies are called
