9.6
Explanation:
to convert km to miles multiply by 1.609
False
As we know that, the Balmer series gives the n values as,
.
Now the value of wavelength can be calculated as,
Here, .
And .
Now,
Therefore,
Therefore, the wavelength of Balmer series lies in visible region which is 547 nm.
idk
.439 Hz
Wavelength = 6.6 m
speed = 2.9 m/s
2.9 = 6.6 f
f = 2.9/6.6 = .439 Hz
