I’d say D sorry if I was wrong
When a valence electron shell becomes full, it will usually become stable.
Answer:
None of the wavelength is in the visible range
Explanation:
Constructive interference of the reflected waves for different wavelengths can be estimated using:
λ = 2nd/m
where m is 1,2,3, ...
Therefore:
m=1, λ = 750 nm
m=2, λ = 750/2 = 375 nm
The limits of eye's sensitivity is between 430 nm and 690 nm. Beyond this range, the eye's sensitivity drops to approximately 1% of its maximum value.
Radiation - it travels in all directions so when you place your hands above a fire radiation hits your hand and reveals to ur cells where they transfer that hear into electrical signals, making you feel heated
