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

Instead of getting further away, Andromeda is actually getting closer and closer. Right now, we are getting closer at a rate of 300 kilometers per … Continue reading Blog 3 – The Great Collision Continue reading

Gravity

Gravity is a fascinating phenomenon of physics that is integral to understanding the universe.  Gravity keeps Earth in orbit around the sun, and the Moon in orbit around Earth.  Any object that has mass, also has gravity. Moreover, the gravitational force between two objects is caused by two factors: mass and distance.  The gravitational force … Continue reading Gravity Continue reading

Blog 2 – Archeoastronomy

For this post, I’ve chosen to write about archeoastronomy in the ancient Peruvian city of Machu Picchu. I will be visiting the city this summer, which is perfect for this blog! First, a little bit about archeoastronomy. Archeoastronomy is the study of astronomical knowledge from ancient societies and civilizations. Machu Picchu is hidden away in … Continue reading Blog 2 – Archeoastronomy Continue reading
