Given,
Frequency of a source moving towards object = 4 x 10¹⁴ Hz
The velocity of a source moving towards object = 1.2 x 10⁷ m/s
To find,
Doppler shift in frequency.
Solution,
We know, that the doppler shift in frequency is given by the formula -
Doppler shift frequency = × relative velocity / speed of light
Therefore, the doppler shift in frequency for this question is -
⇒ × relative velocity/speed of light
⇒ 4 x 10¹⁴ Hz × 1.2 x 10⁷ m/s / 3 × 10⁸ m/s
⇒ 4 x 10¹⁴ Hz × 0.4 × 10⁻¹
⇒ 1.6 × 10¹³ Hz
Hence, the Doppler shift in frequency is 1.6 × 10¹³ Hz
