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,
Therefore, the wavelength of Balmer series lies in visible region which is 547 nm.
Explanation:
Given formula:
ME=mv²+mgh
To make height the subject of the formula, follow the following procedures;
Subtract mv² from both side of equation
M.E - mv² =
mv² -
mv²+mgh
This gives:
M.E - mv² = mgh
Multiply both sides of the expression by
( M.E - mv² ) x
=
x mgh
h = ( M.E - mv² ) x
