Which wave has the greatest wavelength

However, there is the potential for hearing damage from about 80 dB to dB: These are sounds of a food processor, power lawnmower, heavy truck 25 feet away , subway train 20 feet away , live rock music, and a jackhammer. The threshold for pain is about dB, a jet plane taking off or a revolver firing at close range Dunkle, This figure illustrates the loudness of common sounds.

Although wave amplitude is generally associated with loudness, there is some interaction between frequency and amplitude in our perception of loudness within the audible range.

For example, a 10 Hz sound wave is inaudible no matter the amplitude of the wave. A Hz sound wave, on the other hand, would vary dramatically in terms of perceived loudness as the amplitude of the wave increased. Watch this brief video demonstrating how frequency and amplitude interact in our perception of loudness. Of course, different musical instruments can play the same musical note at the same level of loudness, yet they still sound quite different.

This is known as the timbre of a sound. Watch this video that provides additional information on sound waves. Both light and sound can be described in terms of wave forms with physical characteristics like amplitude, wavelength, and timbre. Wavelength and frequency are inversely related so that longer waves have lower frequencies, and shorter waves have higher frequencies.

Why do you think other species have such different ranges of sensitivity for both visual and auditory stimuli compared to humans? Why do you think humans are especially sensitive to sounds with frequencies that fall in the middle portion of the audible range? How would you explain this to a friend who never had the opportunity to take a class like this? Other species have evolved to best suit their particular environmental niches.

For example, the honeybee relies on flowering plants for survival. Seeing in the ultraviolet light might prove especially helpful when locating flowers. Once a flower is found, the ultraviolet rays point to the center of the flower where the pollen and nectar are contained.

Similar arguments could be made for infrared detection in snakes as well as for the differences in audible ranges of the species described in this section. Once again, one could make an evolutionary argument here. Wavelength is the distance between one wave crest to the next. Waves in the electromagnetic spectrum vary in size from very long radio waves the size of buildings, to very short gamma-rays smaller than the size of the nucleus of an atom.

Did you know that electromagnetic waves can not only be described by their wavelength, but also by their energy and frequency? What color has the highest frequency and the shortest wavelength.

If you're moving from radio waves to ultraviolet waves, describe how the energy level changes. Energy level doesn't change. We never talked about it. If you're moving from gamma rays to microwave, describe how the energy level changes.

Put the visible light colors in order from longest wavelength to shortest wavelength. All waves carry. Which wave has a longer wavelength? Which wave has a greater frequency?
