   physics.stackexchange.com › questions › 29583

   The speed of light in vacuum is constant and does not depend on characteristics of the wave (e.g. its frequency, polarization, etc). In other words, in vacuum blue and red colored light travel at the same speed c.

   May 24, 2024 · We know that light is a wave based on how it behaves – it exhibits the same properties of other waves we have examined – it interferes with itself, it follows an inverse-square law for intensity (brightness), and so on.

   Jul 27, 2023 · Relate the wavelength and frequency of light using a mathematical equation. Define electromagnetic radiation. Light is a little different from sound waves, water waves and string waves, because it can move through a vacuum. In general, the velocity of light is constant, c = 3.00 x 10 8 m/s.

   Whereas water waves may travel a few meters per second, the speed of sound in dry air at 20°C is 343.5 m/s. Ultrasonic waves, which travel at an even higher speed (>1500 m/s) and have a greater frequency, are used in such diverse applications as locating underwater objects and the medical imaging of internal organs.

   Can light travel faster than sound?

   • Not even Superman managed that. In fact, nothing can travel faster than the speed of light. By comparison, sound travels just 340 m in one second, about the length of three and a half hockey pitches. The table summarises some similarities and differences between light waves and sound waves:

   What is the speed of a wave?

   • The speed of a wave is equal to the product of its wavelength and frequency. Electromagnetic radiation consists of two perpendicular waves, one electric and one magnetic, propagating at the speed of light (c).

   Is light a wave?

   • This difficulty gets greatly magnified for the case of light. We know that light is a wave based on how it behaves – it exhibits the same properties of other waves we have examined – it interferes with itself, it follows an inverse-square law for intensity (brightness), and so on.

   Does red light travel faster than blue in glass?

   • Red light travels faster than blue in glass. As far as we know, light is mediated by a particle without rest mass. Special relativity says that such a massless particle's speed must always be observed to be c c, irrespective of the observer's motion. In general relativity, a massless particle's speed as measured locally is also always c c.

   What is the speed of light in vacuum?

   • The speed of light in vacuum is constant and does not depend on characteristics of the wave (e.g. its frequency, polarization, etc). In other words, in vacuum blue and red colored light travel at the same speed c. The propagation of light in a medium involves complex interactions between the wave and the material through which it travels.

   Why do different types of electromagnetic radiation differ in wavelength and frequency?

   • Because the various kinds of electromagnetic radiation all have the same speed (c), they differ in only wavelength and frequency. As shown in Figure 1.1.4 and Table 1.1.1 , the wavelengths of familiar electromagnetic radiation range from 10 1 m for radio waves to 10 −12 m for gamma rays, which are emitted by nuclear reactions.

   Oct 21, 2024 · In his formulation of electromagnetism, Maxwell described light as a propagating wave of electric and magnetic fields. More generally, he predicted the existence of electromagnetic radiation: coupled electric and magnetic fields traveling as waves at a speed equal to the known speed of light.
