A mobile phone tower transmits a wave signal of frequency 900 MHz. Calculate the length of the wave transmitted from the mobile phone tower .

A

0.33 m

B

300 m

C

`2700 xx 10^(8)` m

D

1200 m

Text Solution

Verified by Experts

`f = 900 "MHz" = 900 xx 10^(6)` Hz
Speed of wave (c) = `3 xx 10^(8) ms^(-1)`
`lamda = v/f = (3xx10^(8))/(900xx10^(6)) = 1/3 = 0.33` m

A ship in a sea sends SONAR waves straight down into the seawater from the bottom of the ship. The signal reflects from the deep bottom bed rock and returns to the ship after 3.5 s. After the ship moves to 100 Km it sends another signal which returns back after 2s. Calculate the depth of the sea in each case and also compute the difference in height between two cases.

The angle of elevation of the top of cell phone tower from the foot of a high apartment is 60^(@) and the angle of depression of the foot of the tower from the top of the apartment is 30^(@) . If the height of the apartment is 50m , find the height of the cell tower. According to radiations control norms, the minimum height of the cell phone tower should be 120m. State if the height of the above mentioned cell phone tower meets the radiation norms.
