Infrared, ultraviolet, and visible radiation are all part of the electromagnetic spectrum.
Arrange the three types of radiation in order of increasing energy?
i put visible<infrared<ultraviolet. Is this correct though
Close but no cigar. You can make an educated guess by remembering that
E = hf. You know uv is high frequency(short wavelength) so it will have the most energy. Infrared is low frequency (high wavelength) so it will have the least energy. Visible radiation is between. BTW, the problem you had the other night where I suggested it might be the number of significant digits. It was a percent problem. How did that work out?
u were right on that significant figure. Thanks for the help
