How can you tell the waves from the Sun are electromagnetic waves?

Light is a wave in e local electric and magnetic fields. The light we see has wavelength ms of 400 to 700 nanometers, and this happened to be the types of electromagnetic waves the Sun gives off most of its energy in and it does so pretty steadily.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
