$[$Isotropic radiation$]$

A $60-$watt light bulb emits light uniformly in all directions.

$-$ At a point $1$ meter from the bulb, compute the following:

$($a$)$ Intensity $($in W$/$m$^\{2\})$

$($b$)$ Amplitude of the electric field $[$V$/$m$]$

$($c$)$ Amplitude of the magnetic field $[$T$]$

$($d$)($average$)$ energy density $($J$/$m$^\{3\})$

$-$ At a point $2$ meters from the bulb, compute the following:

$($f$)$ Intensity $($in W$/$m$^\{2\})$

$($g$)$ Amplitude of the electric field $[$V$/$m$]$

$($h$)$ Amplitude of the magnetic field $[$T$]$

$($i$)($average$)$ energy density $($J$/$m$^\{3\})$
