A lossless transmission line of 50 ohms impedance is connected to a resistive load of 80 ohms. Find the reflection coefficient (defined in terms of voltages), the standing wave ratio and the input impedance of the line assuming the length of line as a) one-quarter wavelength and b) one-half wavelength. Comment on the result you found in the latter.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
