TV waves have a wavelength range of 1-10 meter. Their frequency range in MHz is Options: A . &nbsp30-300 B . &nbsp3-30 C . &nbsp300-3000 D . &nbsp3-3000

Answer: Option A : A v = C λ ⇒ v 1 = 3 × 10 8 1 = 3 × 10 8 Hz=300 MHz and v 2 = 3 × 10 8 10 = 3 × 10 7 Hz=30 MHz

TV waves have a wavelength range of 1-10 meter. Their frequency range in MHz is

Question

TV waves have a wavelength range of 1-10 meter. Their frequency range in MHz is

Options:

A . 30-300

B . 3-30

C . 300-3000

D . 3-3000

Answer: Option A
:
A

v = \frac{C}{λ} \Rightarrow v_{1} = \frac{3 \times 10^{8}}{1} = 3 \times 10^{8}

Hz=300 MHz
and

v_{2} = \frac{3 \times 10^{8}}{10} = 3 \times 10^{7}

Hz=30 MHz
