When water has a temperature greater than 100c, it's boiling
Answer:
Explanation:
For constructive interference in thin films by reflected light , the condition is
Path difference = 2μd = odd multiple of λ / 2
Where μ is refractive index of water , d is thickness of water medium and λ
is wavelength of light
λ = 4μd or 4μd / 3 or 4μd / 5
= 4 x 1.33 x 400 nm = 2128 nm
or 2128 /3 = 709.33 nm
or 2128 /5 = 425.6 nm
For destructive interference ( dim reflection )
2μd = multiple of λ = λ or 2λ or 3λ
2 x 1.33 x 400 nm =1064
or 1064 x 2 = 2128 nm
or 1064 x 3 = 3192 nm.
