Question

A transmitter produces radio waves of wavelength 1500m. It takes the waves 0.025s to travel from transmitter to radio receiver.

What is the distance between the radio transmitter and the receiver?
A) 5 × 10³ m
B) 2 × 10⁵ m
C) 7.5 × 10⁶ m
D) 1.1 × 10¹⁰ m​

Answer 1

`7.5 * 10 {}^(6)`

Step-by-step explanation:

Speed of electromagnetic waves=

`3 * 10 {}^(8) ms`

m/s

`= 3 * 10 {}^(8) ms * 0.025`

`= 3 * 10 {}^(8) * (1)/(40)`

`= 7.5 * 10 {}^(6) m`
