What is the energy of a radio wave photon with a frequency of 1.255 x 106 sec-1 ?

a. 1.202 x 10^ 27 J
b. 239.0 J
c. 8.316 x 10^-28 J
d. 1.255 J
e. 1.255 x 10^-19 J

The correct answer is option c.

Explanation:

where,

E = energy of photon = ?

h = Planck's constant =

=- frequency of the wave

c = speed of light =

= wavelength of the radio wave photon

Now put all the given values in the above formula, we get the energy of the photons.

Hence, the correct answer is option c.

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
