Students were asked to catch a dropped ruler during each of two conditions: while they were talking on their cellphone, and when they were not doing anything. The data shows their reaction time in milliseconds. Data are arranged from lowest to highest (fastest time to slowest time).

An electromagnetic wave with frequency 65.0 hz travels in aninsulating magnetic material that has dielectric constant 3.64 andrelative permeability 5.18 at this frequency. the electric fieldhas amplitude 7.20 \times 10^{ - 3} {\rm v}/{\rm m}. a. what is the speed of propagation of the wave? b.what is the wavelength of the wave? c.what is the amplitude of the magnetic field? d.what is the intensity of the wave?
