In this way standing waves are set up.The way in which the effect occurs can be demonstrated with a length of rope. If one end is left free and the other is moved up an down the wave motion can be seen to move
Standing wave ratio (SWR) is the measurement of a type of impedance mismatch that can cause poor transmission efficiency in radio engineering. Impedance mismatch may cause standing waves along the transmission line. Advertisements Standing wave ratio is also known as voltage standing wave ratio (VSW...
Voltage Standing Wave Ratio (VSWR) is defined as the ratio between the incident and reflected wave in an RF component or system. It determines the efficiency of power transmission from a source to the load through a transmission line (or cable). The minimum value of VSWR can be 1:1 (or...

Einstein also says this occurs due to gravity — but in his theory, gravity is not a force. It's a curve in space-time. According to Einstein, those objects are still traveling along the straightest possible line, but due to a distortion in space-time, the straightest possible line is...
But if a mass of delivery drivers or riders had failed to show up for work, the last-mile delivery sector would have become paralysed, leaving individuals in various states of lockdown or isolation without food and supplies. As the sector is poised to retain its importance in the post-...
As a medical student, Mayer did a rotation in an intensive care unit. “Having a loved one who is very ill is always incredibly difficult, and it is even more difficult when it is not known what their wishes are. Taking that tension away is something I wanted ...

Line of sight is a vital factor inwirelesscommunication. Some forms of wireless transmission are completely blocked if anything comes between the transmitter and receiver. Other forms of transmission can penetrate less dense objects, like walls and building, but are blocked by large objects, like mo...
For the standing wave (please visit link above to understand first): And for the power transmitted and reflected: With some values we have tabulated the table below. Here comes a good tip: Understand the return loss as 'How much weaker, in dB, the reflected unwanted signal is, compared wi...
