Read the following passage carefully and answer the questions that follow:

The Hidden Language of Light

For centuries, astronomers gazed at the night sky, marvelling at the twinkling stars and the hazy glow of distant galaxies. However, these celestial objects whispered secrets in a language invisible to the naked eye – the language of light. Light isn't just what allows us to see; it carries a wealth of information. By analysing the spectrum, the breakdown of light into its component colours, scientists can unlock the composition, temperature, and even motion of celestial bodies.

One key discovery was the existence of elements beyond Earth. When a hot star burns, its atoms emit specific wavelengths of light, like a unique fingerprint. By comparing these fingerprints to the spectra of elements found on Earth, scientists can identify the presence of elements like hydrogen, helium, and even iron in distant stars. Additionally, the Doppler effect, where the observed frequency of light shifts depending on the motion of the source, allows us to measure the speed at which stars and galaxies are moving away from or towards us. This information helps us understand the vastness and evolution of the universe.

The language of light has revolutionized astronomy, transforming our understanding of the cosmos from a place of wonder to a vast laboratory filled with secrets waiting to be unravelled.
