What is the wavelength of an electromagnetic wave that travels at 3 x 10^8 m/s and has a frequency of 60 mhz? (1 mhz = 1,000,000 hz)?

5m

Explanation:

Given parameters:

Speed of wave  = 3 x 10⁸m/s

Frequency  = 60mhz  = 60 x 10⁶Hz

Unknown:

wavelength = ?

Solution:

To solve this problem;

 we use the expression:

                      V = F ∧  

V is the velocity

F is the frequency

∧ is the wavelength

  Now insert the parameters and solve;

              3 x 10⁸   = 60 x 10⁶ x ∧  

 So;

        ∧   = 5m

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
