- It takee 3.8 x10^-5s for a pulse of radio waves from a radar to reach a plane and bounce back.How far is the plane from the radar?Pulsed lasers used in science and medicine produce very short bursts of electromagnetic energy. If the laser light wavelength is 1062 nmnm (Neodymium-YAG laser), and the pulse lasts for 35 picoseconds, how many wavelengths are found within the laser pulse? Assume that the wave travels in free space. Express your answer using two significant figures. How brief would the pulse need to be to fit only one wavelength? Express your answer to three significant figures and include the appropriate units.An airborn radar of an airoplane has a pulse width of 5µ sec, at a vertical height of1nautical mile,A. find the lateral ground distance on earth to land,B. find the angle to be maintained for proper landing with above values.

What length in inches of the optic cable represents 0.75 ms(millisecond)?Two different kinds of traveling waves 1 and 2 are described by the wave functions shown.
