Q1: The electric field in a monochromatic electromagnetic (em) wave propagating in free space is expressed by E (x, t) = y 150 sin (107 x - w t) V/m, where x and t are in meters and seconds, respectively. The experimentally measured energy density (in uJ/m³) stored in this em wave would be a) 0.1 b) 0.05 c) 0.2 d) zero
