In physics, what does the letter G stand for? What does a carrot over a letter mean in physics? Using a suitable example, explain what is meant by the term Galilean Relativity. What is the definition for Huygens principle? Define what is a free-fall motion?
How does frequency relate to energy? In electromagnetic waves, higher frequency means higher energy. 12 Do longer wavelengths always mean lower frequencies? Yes, for a given wave speed, longer wavelength corresponds to lower frequency. 11 How are frequency and wavelength used in communication? Radios...
What does Electromagnetic Mean? The term "electromagnetic" simply means "related to electromagnetism." Electromagnetism refers to the two overlapping worlds of magnetism and electricity in the scientific context. Although electricity and magnetism were discovered independently, electromagnetism is now considered...
What does solid mean in physics? In physics, solid refers to one of the three basic states of matter with a definite shape and volume, characterized by structural rigidity. 12 Is glass considered solid or hard? Glass is considered both solid and hard; it maintains a fixed shape and is als...
Why frequency does not change in refraction? During refraction, what happens to a wave when it travels from one medium to another? Explain about reflection and refraction at ray diagrams. How does the index of refraction show density? What does refraction mean in terms of rainbows? For refracti...
Most of my career so far has focused on software testing in one form or another. What is testing if not verifying the quality of the object under test? But what does the word quality really mean? It is hard to define quality, but I will argue that a good operating definition is fitnes...
We assume 𝑆𝜈∼𝜈−𝛼Sν∼ν−α, where 𝑆𝜈Sν is the flux density (expressed in Jy, mJy, etc.) at a given frequency 𝜈ν, and 𝛼α is the spectral index. 2. Observational Evidence for Jets in RQ AGN We note that the radio properties of RQ AGN are also ...
