- A uniform plane wave has a wavelength of 2 cm in free space and 1 cm in a perfect dielectric. What is tbe relative permittivity of the of the dielectric ?arrow_forwardHW 1) what is the maximum strength of the 8 field in an electromagnetic wave that has a maximum E-field strength of 1000 V/m? 2) The beam from a small laboratory laser typically has an intensity of about 1.0 x 10-3 W/m2 . Assuming that the beam is composed of plane waves, calculate the amplitudes of the electric and magnetic fields in the beam. 3) A 60-kW radio transmitter on Earth sends its signal to a satellite 100 km away (below). At what distance in the same direction would the signal have the same maximum field strength if the transmitter's output power were increased to 90 kW?arrow_forward4. When a plane wave of monochromatic visible light falls normally on a plate with a circular hole (radius of the hole is r = 0.5mm), a dark spot appears at the center of the optical axis, which has a distance of 20cm away from the diffraction hole. Calculate the wavelength of this visible light.arrow_forward
