He proposed that light was emitted in all directions as being a series of waves inside a medium known as the luminiferous aether. As waves will not be afflicted by gravity, it absolutely was assumed they slowed down upon moving into a denser medium.[37] A different supporter of your wave idea was Leonhard Euler. He argued in Nova theoria lucis et colorum (1746) that diffraction could extra conveniently be stated by a wave principle.
Conversation: Wavelength and frequency are vital in television broadcasting, where distinctive frequencies are used to transmit alerts.
Quite simply, it will turn into exactly what is now termed a black gap.
