If electromagnetic radiation has a frequency of 2.0 x 10^15 s^-1 what is the radiation’s energy?

Great amounts of electromagnetic energy from our sun and other bodies in space travel through space. which is a logical conclusion about these electromagnetic waves? their energy must be very their frequency must be very low these waves can travel without a medium they only travel through a vacuum of space
