Answer:
In order for frost to be formed, you would need high humidity, below-freezing temperatures, a clear sky, and a calm wind. Also, note that frost mostly occurs on a surface that is solid, so I would also put in a hard surface to the answer.
Explanation:
You need the hard surface so that the frost can form, otherwise it would become something like a cloud.
You need high humidity so that there is lots of water to form on your solid surface.
You need below-freezing temperatures so that the water can freeze.
The other things are just from what the Internet told me.

Answer:
Option (b) "174 nm"
Explanation:
Energy of emitted photon is 7.13 eV.
We need to find the wavelength of the photon.
1 eV = 1.6 × 10⁻¹⁹ J
Energy of a photon is given by :

Where,
is wavelength of the photon
Putting all the values,

So, the wavelength of the photon is 174 nm.
