Question

A radio station operates at a frequency of 1370 kHz. Express this frequency in GHz.

Answer 1

Answer ⇒ The Frequency in GHz is 1.37 × 10⁻³ GHz.

Explanation ⇒ From the Knowledge of Prefix used in units.

We know that 1 G is used to represent, 10⁹

Now, Given frequency,

f = 1370 kHz.

∴ f = 1370000 Hz.

Multiplying and dividing by 10⁹, we will get,

f = 1370000 × 10⁹/10⁹

f = 1370000 × 10⁻⁹ GHz.

f = 1.37 × 10⁻³ GHz.

Hence, the Frequency in GHz is 1.37 × 10⁻³ GHz.

Hope it helps.

Answer 2

Answer:

f = 1370 kHz.

∴ f = 1370000 Hz.

Multiplying and dividing by 10⁹, we will get,

f = 1370000 × 10⁹/10⁹

f = 1370000 × 10⁻⁹ GHz.

f = 1.37 × 10⁻³ GHz.
