To Calculate: The
Answer to Problem 17PP
The observed frequency is
Explanation of Solution
Given:
The speed of the hydrogen atom is
Frequency emitted by hydrogen atom is
Formula used:
The expression for observed frequency is
Here,
Calculation:
Since the galaxy and the astronomer are moving from each other, therefore negative sign should be selected.
Equation (1) becomes,
Substitute
Conclusion:
Hence, the observed frequency is
