Around1015Hz corresponds to the region of the electromagnetic spectrum...
The electromagnetic spectrum is divided into the following regions:

Gamma-rays 
[wavelength 10^-14 m - 10^-11 m, frequency 10^22 Hz – 10^19 Hz, 

X-rays
[wavelength 10^-12 m - 10^-8 m, frequency 10^20 Hz –10^16 Hz, 

Ultraviolet radiation
[wavelength 10^-8 m - 10^-6 m, frequency 10^17 Hz – 10^15 Hz, 

Visible light
[wavelength 10^-7 m - 10^-6 m, frequency 10^15 Hz – 10^14 Hz, 

Infrared radiation
[wavelength 10^-6 m -10^-3 m, frequency 10^14 Hz – 10^12 Hz, 

Microwaves
[wavelength 10^-4 m – 10^-1 m, frequency 10^13 Hz – 10^9 Hz, 

Radio waves
[wavelength 10 m – 10^3 m, frequency 10^8 Hz – 10^6 Hz,

Around1015Hz corresponds to the region of the electromagnetic spectrum...
To determine the maximum number of electrons in a subshell with l=3 and n=4, we need to use the formula:

Maximum number of electrons in a subshell = 2(2l + 1)

Here, l=3. Plugging in the values, we get:

Maximum number of electrons in a subshell = 2(2(3) + 1) = 2(7) = 14

Therefore, the correct answer is option C, 14.

Around1015Hz corresponds to the region of the electromagnetic spectrum...
Since the wavelength of visible region comes in the order of 10^-7,as you know frequency = C /wavelength. The order of frequency comes 10^15.
