We know that light is a wave but does it require a medium to propagate.If yes then what is that medium.
If light is a wave, what is the medium that is "waving"?
How are visible light waves produced? What are waves? What is a wave in electronics? What are some examples of light refraction in daily life? How light is a transverse wave? What is wave and vibration? What is visible light and how can it be used? What is a sound wave? A wave with a long wavelength has a relatively? What is the mechanical wave? What is the light reflection? What are non-mechanical waves? How would you describe waves? Can sound waves vibrate light waves? Refraction of light is an example of which property of photons? What is frequency of light? What is scattering of light? Can electromagnetic waves be reflected? What creates waves? What creates a wave? What are sound waves? What propels light? What objects reflect light? What is this light? Why does waveboard acclerate when waved? What's in Crystal Light? What is wave motion? Does a low frequency wave or a high frequency wave have a longer wavelength? Do magnetic waves need a medium to propagate? How does the reflection of waves affect specular reflection?
