Ignore my answers because they are wrong.

The wavelength of the radio wave is 3.003 m.

The energy of the radio wave is .

Explanation:

Frequency of the radio waves, ν = 99.9 MHz =

Wavelength and frequency are related to each other by realtion:

= Wavelength of the wave

c = speed of the light

ν = Frequency of the wave

The wavelength of the radio wave is 3.003 m.

The energy of the electromagnetic wave is given by Planck's equation:

h = Planck's constant =

The energy of the radio wave with 99.9 MHz frequency will be:

The energy of the radio wave is .

The  hybridization  of  the   central  carbon  compound  CH4  tetrahedral  is
SP^3 hybridization 

In   tetrahedral  molecular  geometry    a central atom  is  located  at the  center  with  4  substituent  that  are located at  the  corners  of  tetrahedron. Example  in methane  molecules  is made  up of  b equally  spaced sp^3  hybrid  orbital  forming  bond  angle  of   109.5
