How do radio waves differ from visible light

Radio waves actually travel at the speed of light in vacuum, which is about 300,000,000 meters per second. It is fast enough for anyone on Earth to contact others on Earth in less a second. Radio waves are electromagnetic waves, so is light. The differences between light and radio waves are their frequencies and wavelengths. Wavelengths … Continue reading How do radio waves differ from visible light Continue reading

Light in the Universe

Light is a very meaningful aspect of the universe that allowed us to make the observations about space that we have made so far. ┬áThe light that stars produce allows us to determine many things about them. ┬áTheir absorption line spectra allow us to determine their composition and the Doppler effect allows us to determine […] Continue reading
