Spectrum Explained: The Colors of Light

The video tutorial explains the concept of spectrum, which is an array of waves ordered by physical properties like wavelength or frequency. It classifies spectrum into emission and absorption types. Emission spectrum is further divided into continuous and discontinuous spectrums. Continuous spectrum is characterized by a seamless range of colors, while discontinuous spectrum includes line and band spectrums. The video also covers the visible spectrum and natural phenomena like rainbows. It highlights the atomic spectrum as a fingerprint of elements, providing examples like hydrogen and sodium spectrums.

What are the two main types of spectra mentioned in the video?

• Emission and Absorption

• Continuous and Discontinuous

• Visible and Invisible

• Line and Band

Which spectrum is characterized by the absence of gaps between colors?

• Atomic Spectrum

• Band Spectrum

• Continuous Spectrum

• Discontinuous Spectrum

What natural phenomenon is an example of a continuous spectrum?

• Solar Eclipse

• Rainbow

• Thunderstorm

• Aurora Borealis

What is the characteristic feature of an atomic spectrum?

• It is continuous without gaps

• It is visible to the human eye

• It is specific to molecules

• It consists of bright lines specific to atoms

Which of the following is an example of an atomic spectrum?

• Rainbow

• Hydrogen Spectrum

• Visible Spectrum

• Band Spectrum
