Question

a radio can tune i to any station in7.5MHz to 12MHz band.what is the corresponding wavelength band​

Answer 1

Answer:

40m to 25m

Explanation:

Given ,

A radio can tune to min. frq.

V1 = 7.5MHz = 7.5 x 10^6 Hz

Max freq .

V2 = 12 MHz = 12 x 10 ^6

Speed light ,

C = 3 x 10 ^8 m/s

wave length  (λ) for V1

λ1 = c / V1

   = 3 x 10 ^8 / 7.5 x 10 ^6

    = 40 m

for V2 ,

λ2 = c / V2

     = 3 x 10 ^8 / 12 x 10^6

      = 25 m

Hence , the wave length band of the radio is 40 m to 25 m .

Question 5

A radio can tune in to any station in the 7.5 MHz to 12 MHz band. What is the corresponding wavelength band?

Answer

A radio can tune to minimum frequency, ν1 = 7.5 MHz= 7.5 × 106 Hz

Maximum frequency, ν2 = 12 MHz = 12 × 106 Hz

Speed of light, c = 3 × 108 m/s

Corresponding wavelength for ν1 can be calculated as:

please mark me brainliest ✌️

Corresponding wavelength for ν2 can be calculated as:

Thus, the wavelength band of the radio is 40 m to 25 m.
