An electromagnetic wave has a frequency of 3.0 x 105 hz. what is the
wavelength of the wave? use the equation 2 = and the speed of light as 3.0
x 108 m/s.
o a. 9.0 x 103 m
o b. 9.0x1013 m
o c. 1.0 x 103 m
o d. 1.0 x 1013 m

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

What makes thermal imaging cameras useful? they can detect differences in color. they can detect differences in wave speeds. they can detect differences in temperature. they can detect mechanical waves.
