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 = f_{carrier} × relative velocity / speed of light

Therefore, the doppler shift in frequency for this question is -

f_{carrier} × 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
