Since high frequency light moves the air more rapidly, it makes sense that the molecules will have to fight viscosity more than when a low frequency wave passes. Why do low frequency waves diffract more? Wave always carry energy infinite distance. Oh I meant to say sound waves. This has to do with the way sound waves travel through the air. Why do low frequency sounds travel better over hills? @EmilioPisanty diffraction is almost certainly a factor however estimating how much of a factor seems hard, especially with the variation in headphones and other room configurations. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Whenever you give molecules a "push" you're going to lose some energy to heat. Both sound and light has the same nature of wavelength propagation. Frequency is expressed in units of cycles per unit time. Mr. Enright's answer addresses the first, taught us a lot, and answered the basic question. So as f increases, 1 / f decreases. Low frequency sound waves are able to travel further than high frequency sound waves for a variety of reasons. As a result, FM waves cannot reach very distant receivers. "like 500nm, which can be similar to the size of air molecules.". : 261 As a form of electromagnetic radiation, like light waves, radio waves are affected by the phenomena of reflection, refraction, diffraction, absorption, polarization, and scattering. Low frequency waves are produced by slow vibrations while high frequency waves are produced by fast vibrations.So low frequency waves have less energy because they are produced by slow vibrations. Because the waves are reflected, they can reach radio receivers that are very far away from the radio tower. This cookie is set by GDPR Cookie Consent plugin.

Therefore, the power radiated into the space increases and signal can travel larger distance. It depends on how thick the wall is and how thick the concrete is. If so, our speech signal is low frequency signal, why it is not travelling further? Bass sounds have wavelength about the size of the objects and waveguides in their path, whereas higher sounds are progressively deeper into the ray optics regime. When you say lower frequency waves travel far, you are referring to electromagnetic waves that travel longer distances compared to higher frequency electromagnetic waves such TV waves. Thus, the transmitted power is constant. In general, low frequency waves travel further than high frequency waves because there is less energy transferred to the medium. high frequency light travels slightly faster than low frequency light and separates over very long distances. How can I recognize one? Remember, sound is a pressure wave vibration of molecules. Also, in AM the transmitted power goes waste in the transmitted carrier.
