WebElectromagnetic waves always travel at the same speed (299,792 km per second). This is one of their defining characteristics. spectrum there are many different types of waves with varying frequencies and wavelengths. They are all related by one important equation: Any electromagnetic Electromagnetic waves are typically described by any of the following three physical properties: the frequency f, wavelength λ, or photon energy E. Frequencies observed in astronomy range from 2.4×10 Hz (1 GeV gamma rays) down to the local plasma frequency of the ionized interstellar medium (~1 kHz). Wavelength is inversely proportional to the wave frequency, so gamma rays have very short wavelengths that are fractions of the size of atoms, whereas wavelengths on the … WebWe see the sky blue in colour as shorter wavelengths of light are scattered more by the atmosphere. Blue has one of the shortest wavelengths in the visible spectrum. Violet and Indigo have a shorter wavelength than blue and so are scattered more but our eyes are more sensitive to Blue light as to Violet and Indigo light. 3 comments ( 23 votes) screen mirror app free
