摘要: Questions and answers related to astronomy are presented, including a question asking what radio telescopes observe and how it relates to the visible sky, how many stars are contained in the Milky Way galaxy, and if dark matter coalesces like ordinary matter....
What type of electromagnetic waves are emitted from the sun? Which type of electromagnetic radiation is lowest in energy? What produces electricity from a magnetic field? Sunlight is a form of energy called How does an electron emit a photon of light?

This drop-off of power at higher frequencies produces deeper sounds, like a low, distant rumbling or a steady wind. This article was updated in conjunction with AI technology, then fact-checked and edited by a HowStuffWorks editor. Frequently Answered Questions What does white noise do? White ...
an ac motor designed to operate at 60 Hz runs slower if the frequency drops below 60 Hz, faster if it exceeds 60 Hz. For ac motors, any change in frequency causes a proportional change in motor speed. Another example is a 5% reduction in frequency produces a 5% reduction in motor speed...
A spark-gap transmitter produces electromagnetic waves that can be picked up on a receiver tuned to a specific frequency. The development of this technology laid the groundwork for widespread radio communication around the world. Although it is not in wide use today because of its inefficiency and...
A radioactive substance produces several types of radiation, some of which are dangerous to live organisms. Learn the three types of radiation, explore radioactive substances, and discover examples of how we use them to our benefit. What is Radiation? When Bruce Banner gets angry, he turns ...
An advanced alarm will also include a separate siren that produces a variety of piercing sounds. Making a lot of noise brings attention to the car thief, and many intruders will flee the scene as soon as the alarm blares. Car Alarm Transmitters The keychain transmitter from the Sidewinder ...
So, until the theory is proved wrong or a simpler theory produces the same results, SR will maintain its position as the best theory out there. Here are five concepts you have discovered in this article: There is no such thing as an absolute (completely stationary) frame of reference. The...
