Question

Explain about line spectrum and continuous spectrum

Answer 1

A continuous spectrum is a record formed by collecting light of all frequencies traveling through space together. ... A line spectrum is a record formed by collecting light emitted from excited atoms whose electrons are falling back down to lower energy states.

Answer 2

★ SPECTRUM:-

→ A series of radiation arranged in the increasing order of their wavelength is called a spectrum.

★ Types of spectrum:-

There are three types of spectrum.

→ Continuous spectrum

→ Absorption spectrum

→ Emission spectrum

• Continuous Spectrum: The spectrum of white light ranging from violet at 7.5 x 10¹⁴ Hz to red at 4 x 10¹⁴ Hz is called continuous spectrum.

• Emission spectrum: The spectrum of radiations emitted by a substance that has absorbed energy is called emission spectrum.

• Absorption spectrum: The spectrum of radiations absorbed by a substance on irradiation with a beam of light called absorption spectrum.
