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

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 . On a particular day, the maximum frequency reflected from the ionosphere is 9 MHz. On another day, it was found to increase by 1 MHz. The ratio of maximum electrom density of the ionosphere on the two days is

On a particular day, the maximum frequency reflected from the ionosphere is 10 MHz. On another day, it was found to increase to 11 MHz. Calculate the ratio of the maximum electron densities of the ionosphere on the two days. Point out a plausible explanation for this.

On a particular day, the maximum frequency reflected from the ionosphere is 9 MHz. On another day. It was found to increase by 1 MHz. Calculate the rate of the maximum electron densities of the ionosphere on the two days

On a particular day , the maximum frequency reflected from the ionosphere is 9 MHz . On another day , it was found to increase by 1 MHz . Calculate , the ratio of the maximum electron densities of the ionosphere on the two days .

On a particular day , the maximum frequency reflected from the ionsphere is 10 MHz . On another day , it was found to decrease to 8 MHz . Calculate the ratio of the maximum electron densities of the ionosphere on the two days .

On a particular day, the maximum frequency reflected from the ionosphere is 12 MHz, On another day, it was found to decrease to 9 MHz. By what percentage the maximum electron density of the ionosphere has been decreased.

On a particular day the maximum frequency reflected from the ionosphere is 8 MHz On next day it was found to increase to 9MHz. If ratio of maximum electron densities of first day to maximum electron densities of next day the ionosphere is n, find value of 81 m.

On a particular day the maximum frequency reflected from the ionosphere is 8 MHz On next day it was found to increase to 9MHz If ratio of maximum electron densities of first day to maximum electron densities of next day the ionosphere is n, find value of 01 m.

On a particular day, the maximum frequency reflected from the ionosphere is 10MHz. After 10 days, it increaesed to 11 MHz. What is the ratio of the maximum electron density of the ionosphere on these two days ?
