The amplitude and wavelength of a water wave are frequently classified based on the depth of the water in which they happen. Ocean waves of great amplitude and long wavelength, for example, are created in the deep ocean as waves of small amplitude but long-wavelength; when they approach the...

emits waves of wavelength 0.2m. How long does it take to travel 300m ? A 70 s B 60 s C 12 s D 3 s Video SolutionText SolutionVerified by Experts The correct Answer is:D v=vλ=(500Hz)(0.2m)=100m/s Time taken by the wave to travel 300m=300m100m/s=3s. Show More ...
There are two basic categories of holograms — transmission and reflection. Transmission holograms create a 3-D image when monochromatic light, or light that is all one wavelength, travels through them. Reflection holograms create a 3-D image when laser light or white light reflects off of their...
Wavelength, the distance between successive compressions or rarefactions, is inversely related to frequency. Thus low frequency sounds have long wavelengths and high frequency sounds have short wavelengths. For this reason, a low sound can travel much further. Certain animals such whales and elephants...

long wavelength. Hemingway says it appears to be "coming towards you", and so is useful for emergency and alarm signs. Black has a different sense. In the West it's associated with death, but that hasn't stopped it becoming a mysterious colour. Hemingway says says it's "very powerful ...
What is the wavelength (in meters) of an electromagnetic wave whose frequency is 7.18 x 108 Hz? A certain electromagnetic wave has a wavelength of 3.25 x 10-7 nm. What is the frequency of the wave? What's the relationship between wavelength and amplitude?...
