On a particular day, the maximum frequency reflected from the ionosphere is 8 MHz. On other day it was found to increase to 9 MHz. Then ratio of maximum electron densities of the ionosphere on two days will be

A

`9/8`

B

`8/9`

C

`81/64`

D

`64/81`

Text Solution

Verified by Experts

The correct Answer is:
4
`v_(C)=9sqrt(N_(max.))`
`therefore (N_(max_(.1)))/N_(max_(.1))=((v_(e_(1)))/v_(e_(2)))^(2)=(8/9)^(2)`

Height h(400=m) from the ground at place A, from which the readiowaves can be transmitted. There is a receive at station B on earth at a distance d(=125km), which can receive the signal from station A. The radiowaves can reach the station B, either through earth's atmosphere or through satellite. There are four main layers in earth's atmosphere named D,E, F_(1) and F_(2) which play effective role in radio communication. The electron density of these layers is 4xx10^(8), 2xx10^(11),5xx10^(11) and 8xx10^(11)m^(-3) . The radius of the earth is 6.4xx10^(6)m .
