Hi! Please help me answering this questions.1.) The wavelength of an electromagnetic wave is measured to be 600 m.a) What is the frequency of the wave?b) What type of EM wave is it?2.) A piece of iron is heated with a torch to a temperature of 900 K. how much more energy does it emit as blackbody radiation at 900 K than it does at room temperature, 300 K?3.) What is the frequency of the EM wave emitted most strongly by a glowing element on a stove with temperature 1500 K?....I hope you could answer it before 1 am strikes!... Thank you!
