Consider the following kinds of electromagnetic waves:

(A) gamma rays
(B) microwaves
(C) radio waves
(D) visible light
(E) 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. If any elements are equal, show their equality in alphabetical order - for example: A > B = C.

(b) Rank the kinds of waves according to their frequencies from highest to lowest. Use only '>' or '=' symbols. If any elements are equal, show their equality in alphabetical order - for example: A > B = C.

(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 alphabetical order - for example: A > B = C.

According to wavelengths in descending order: C, B, D, E and A

According to frequencies in descending order: A, E, D, B and C

According to speeds in vacuum: A =B =C =D =E

Explanation:

in the EM spectrum, radio waves have the longest wavelength while gamma rays have the shortest wavelength.

All EM waves travel with the same speed of in a vacuum.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
