What else gives off radio waves naturally?
What are the harmful effects of excessive exposure to Microwaves,
Infrared, Ultraviolet,X-rays, Gamma rays?
Consider the following kinds of waves.
(i) gamma rays
(ii) microwaves
(iii) radio waves
(iv) visible light
(v) x-rays
(a) Rank the kinds of waves according to their wavelength ranges from those with the largest typical or average
wavelength to the smallest, noting any cases of equality. (Use only ">" or "=" symbols. Do not include any parentheses
around the letters or symbols.)
(b) Rank the kinds of waves according to their frequencies from highest to lowest. (Use only ">" or "=" symbols. Do not
include any parentheses around the letters or symbols.)
(c) Rank the kinds of waves according to their speeds in vacuum from fastest to slowest. (Use only '>' or '=' symbols. If
any elements are equal, show their equality in increasing order - for example: i > ii = iii.)
