The alpha line in the Balmer series is the transition from n=3 to n=2 and with the wavelength of λ=656 nm = 6.56*10^-7 m. To get the frequency we need the formula: v=λ*f where v is the speed of light, λ is the wavelength and f is the frequency, or c=λ*f. c=3*10^8 m/s. To get the frequency: f=c/λ. Now we input the numbers: f=(3*10^8)/(6.56*10^-7)=4.57*10^14 Hz. So the frequency of the light from alpha line is f= 4.57*10^14 Hz.

Galileo called the dark spots on the sun sunspots.
Answer:
¿Es una pregunta de la escuela o de la vida?
Explanation:
K.E.=mv^2/2=>
m=0.15
v=35m/s
0.15•35^2/2
183.75/2=91.87
All we can predict in advance is that you will have made two slices of apple
inedible, and also ruined a cup of milk and a cup of Gatorade.
Concerning the changes that would take place in these three substances,
I personally don't know, and I doubt that it has ever been tried. This would
make a super science experiment that you could do at home !
