The following table gives the wavelength range of some constituents of this electromagnetic spectrum:

S. No.	Wavelength range
1	1 mm to 700 nm
2	400 nm to 1 nm
3	1 nm to 10-3 nm
4	< 10-3 nm

Select the wavelength range and name the electromagnetic waves that are:
(i) widely used in the remote switches of household electronic devices.
(ii) produced in nuclear reactions.
