the picture is in this link : drive.google.com/file/d/1RvNNuKHYp-6cbccNM1YS_2wftfChgYm3/view?usp=sharing

Answer 1

1) From lowest to highest frequency is the same as longest to shortest wavelength: radio, microwaves, x-rays.

2) Can't access the image, but for a wavelength of 0.01m it should be a microwave!
