Answer:- The wavelength is 
and the right option is D.
Solution:- Wavelength is inversely proportional to the frequency and the equation is:
where, 
is the wavelength, c is the speed of light and 
is frequency.
Frequency is 
and the speed of light is 
.
Since, 
So, 
Let's plug in the values in the equation:
Hence, the right option is D) .
Answer:
A

It's very dangerous to go that deep into the ocean due to the water pressure and the coldness, no human can physically comprehend it, so if you do end up diving that deep into the ocean, you will suffocate, crush to death, or freeze very quickly.
According to the Aufbau principle, , electrons orbiting one or more atoms fill the lowest available energy levels before filling higher levels (e.g., 1s before 2s).
