Answer:
False
Explanation:
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,
![\lambda=\frac{6}{109677} cm\\\lambda=547\times 10^{-9} m\\ \lambda=547 nm](https://tex.z-dn.net/?f=%5Clambda%3D%5Cfrac%7B6%7D%7B109677%7D%20cm%5C%5C%5Clambda%3D547%5Ctimes%2010%5E%7B-9%7D%20m%5C%5C%20%5Clambda%3D547%20nm)
Therefore, the wavelength of Balmer series lies in visible region which is 547 nm.
Answer:
Twice
Step-by-Step Explanation:
Time between 7:00 PM and 1:00 AM: 6 hours
Distance: 4818km
Since the distance is 4818km, and the time is 6 hours, you divide 4818 by 6.
803.0000015999 km/h.
The average speed is 803 km/h
Which considering the ideal case scenario if the plane starts at 0 reaches the speed of 803 and the end reduces its speed from 803 to 0. This means we have come across the value of 800 at least twice. Hence, the plane was travelling at a speed of 800 km/h at least 2 times.
