Blocking microwave auditory effect / Frey effect? - Physics Forums
2023年2月28日 · The microwave auditory effect, also known as the Frey effect, is a phenomenon where humans perceive auditory sensations (such as clicks or buzzing sounds) when exposed to certain pulsed microwave frequencies. This effect was first discovered by American neuroscientist Allan H. Frey in the 1960s. How does the microwave auditory effect work?
Hurricanes and the Coriolis effect? - Physics Forums
2024年10月19日 · Do hurricanes experience the Coriolis effect going down or up category after crossing the equator? The Coriolis effect is what makes water spin counter clockwise/clockwise down a drain on either side of the equator. Is this the correct sub forum for this post?
How Does Light Reflect from a Moving Rocket? - Physics Forums
2006年9月24日 · A rocket approaches a mirror on the ground at a speed of 0.90c. The distance D between the front of the rocket and the mirror is 2.4 * 10^12 m, as measured by ground observers, when a light signal is sent from the front of teh rocket. When is the reflected signal received by the rocket as...
Relationship between light intensity and current - Physics Forums
2012年1月19日 · No, the relationship between light intensity and current cannot be reversed. Light intensity is the cause of the current, and the current is the effect of the light intensity. They cannot be interchanged. How can the relationship between light intensity and current be utilized in practical applications?
Calculating the suction force produced by a Venturi - Physics Forums
2010年1月5日 · However, calculations for estimating the suction force can lead to seemingly meaningless results. Substituting known information into the formula for the venturi effect, a pressure difference of 1.035716981*10^9 Pa is obtained. This results in a high suction force of 732105N, which may indicate a misunderstanding of the principle.
What are some real-life applications of overdamping in …
2014年6月6日 · For a real-world lightly damped system, the nonlinear behavior of the damper doesn't have much effect on the approximation that the motion is harmonic, and for practical purposes you can model the system with a linear damper that takes out the same amount of energy per cycle as the real-world nonlinear one.
"Black sun" effect in CMOS sensors - Physics Forums
2015年2月22日 · The "Black sun" effect can be prevented by using a neutral density filter or reducing the exposure time to avoid oversaturating the pixels. Some CMOS sensors also have built-in features to mitigate the effect, such as electronic shutters and anti-blooming circuits. Can the "Black sun" effect be removed from images taken with CMOS sensors?
Effects of Temperature on Flow Rate - Physics Forums
2018年5月4日 · What factors can influence the effect of temperature on flow rate? Aside from temperature, other factors that can influence the effect of temperature on flow rate include the properties of the fluid (such as viscosity and density), the size and shape of the container or pipe, and the type of fluid flow (such as laminar or turbulent).
The Interaction of Sound and Light - Physics Forums
2016年5月16日 · The Photoacoustic Effect. The photoacoustic effect, from the Greek word for light and the Greek for hearing, is a sound emission that originates from a change in density induced by light. A typical example involves a block of stuff that you blast with a laser. The laser blast causes the stuff to rapidly heat up and expand, and that expansion ...
