Does higher frequency mean smaller wavelength?

The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength.

How does the wavelength affect the frequency of the wave?

The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.

Does higher frequency travel further?

Consequently, a sound wave can only propagate through a limited distance. In general, low frequency waves travel further than high frequency waves because there is less energy transferred to the medium. Hence the use of low frequencies for fog horns.

How do you tell if a wave has a higher frequency?

If the distance between the wave crests is large ( i.e. the wavelength is long), then the boat bobs up and down less often ( the frequency is low); if the distance is small ( i.e. the wavelength is short), then the boat bobs up and down more often ( the frequency is high).

How can humans detect infrared waves?

We can sense some infrared energy as heat. Our eyes cannot see these infrared waves but instruments that can sense infrared energy—such as night-vision goggles or infrared cameras–allow us to “see” the infrared waves emitting from warm objects such as humans and animals.
