Answers:
(a)
μT
(b)
μm
(c) f =
Explanation:
Given electric field(in y direction) equation:
(a) The amplitude of electric field is
. Hence
The amplitude of magnetic field oscillations is
Where c = speed of light
Therefore,
μT (Where T is in seconds--signifies the oscillations)
(b) To find the wavelength use:
μm
(c) Since c = fλ
=> f = c/λ
Now plug-in the values
f = (3*10^8)/(0.4488*10^-6)
f =
