Science. 1 … Something that I find interesting but don't really know why… If you wanted the wave to move slower, you would tell them to take their time getting up. As it turns out, the ionosphere reflects certain frequencies of radio waves. The information is imposed on the electromagnetic carrier wave as amplitude modulation (AM) or as frequency modulation (FM) or in digital form (pulse modulation). Why are the bass sounds more audible? Hope this helps lower frequency sounds pass through walls because they have a much bigger wave length. In atmospheric science, an alternative definition is usually given, from 3 Hz to 3 kHz. The answer to this question has to do with the nature of waves. Thank You Why do lower frequency sound waves travel further than higher frequencies? ... then why does a wave with lower energy have the ability to shake stuff more efficiently? Middle C in the treble clef of a piano is a medium sound frequency sound, just a little above 500 Hz. The answer probably has to do with the bass sound waves having the highest wavelengths. LF waves easily penetrate through dense materials like concrete, rock, soil, etc. For example, in sound reinforcement you have to take into account wind speed, temperature and even humidity. As the frequency rises, absorption effects become more important. 0 Comments Add a Comment. In the open air other noises such as traffic may mask the annoying low frequencies. Consequently, a sound wave can only propagate through a limited distance. if signal attenuation is more in low frequency signal then why there is more attenuation in 30/20 GHz band in satellite communication as compared to 6/4 GHz band. To make a wave with higher frequency, that is, to make a wave that goes up down more times in one second, you need the people to stand up and down very fast. ... Posted by 3 hours ago. But why? I thought it was the other way around. It may help to think of low, middle and high-frequency sound with respect to musical notes. When you listen to speakers, or headphones for that matter, from far away, you usually only hear the bass, not the treble. Based on the relation of frequency and wavelengths, the higher the frequency, the shorter the wavelengths and therefore the distance of travel is lower. Why does lower frequency sound travel further? At the same volume or decibel which would travel further? Ask Question Asked 9 years, 1 month ago. And why are higher frequencies much easier to absorb? ... sound waves at low frequencies (if I remember this means a lower pitch) ... it's for the same reason. The culprit may be wind turbines or water pumps miles … April 26, 2017 Frequency high low Travel waves. 1 2. These properties allow high frequency waves to travel further as compared to low frequency waves. Both radio waves and microwaves are used in … Not all radio waves travel farther at night than during the day, but some, short and medium wave, which AM radio signals fall under, definitely can given the right conditions. The way I understand energy, is you need more energy to travel further, like adding gas to a car. Seismic waves are waves of energy that travel through Earth's layers, and are a result of earthquakes, volcanic eruptions, magma movement, large landslides and large man-made explosions that give out low-frequency acoustic energy. Posted by 6 years ago. the ... Lv 7. The process of ‘mounting’ the original signal to a carrier wave is called modulation. does it have anything to do with ratio of size? Why Do Low Pitch Frequency Travel Further Than High Pitch Frequency? What travels further High frequency sound waves or low? Light waves do not travel in media, so for them there isn't any simple explanation for why higher frequency light is higher energy light. this is why you can put bass speakers anywhere in a room and it sounds fine, but the other speakers have to be … 0. Low frequency sound waves take longer to develop and so can travel greater distances than HFN. That's why when your neighbor is playing loud music, the only thing you hear is the base. Re: Why do low frequency waves seem to travel farther than high frequency waves Date: Fri Nov 19 22:10:34 1999 Posted By: John Link, Physics Area of science: Physics ID: 942890407.Ph While maybe slower, sound can travel further distances when it is colder. Unlike a radio signal (which usually has a very low frequency), a carrier signal has a constant amplitude and frequency, i.e. Aren't high frequency waves more energetic than low frequency waves? Therefore HF and lower frequency radiation is the best to use for direct long distance communications (when satellites or long cables cannot be used). Think of dominoes falling. A high frequency sound has a greater wavelength than a low frequency sound. The increase in range is caused by an inversion, which happens when warm air traps cold air near the ground. Why do lower frequency sound waves travel further than higher frequencies? The low frequency will travel farther. Low frequency radio waves do not travel very far through the atmosphere and are absorbed rather quickly. At microwave or higher frequencies, absorption by molecular resonances in the atmosphere (mostly from water, H 2 O and oxygen, O 2 ) is a major factor in radio propagation.
