Select the correct term to complete each sentence.
1. If you ___________ the wavelength, the electromagnetic radiation energy will double.
2. The energy of the electromagnetic radiation will_____________ if you halve the wavenumber.
3. When the frequency of the light is doubled, its energy will___________.
a. halve
b. double

Respuesta :

Answer: 1. halve

2. halve

3. double

Explanation:

The relationship between wavelength and energy of the wave follows the equation:

[tex]E=\frac{hc}{\lambda}[/tex]

E= energy

[tex]\lambda [/tex] = wavelength of the wave

h = Planck's constant  

c = speed of light

Thus as wavelength and energy have inverse realation, when wavelength will halve , energy will double.

2. The between wavenumber and energy of the wave follows the equation:

[tex]E=h\times c\times \bar{\nu}[/tex]

E= energy

[tex]\bar{\nu}[/tex][tex]\nubar[/tex] = wavenumber of the wave

h = Planck's constant  

c = speed of light

Thus as wavenumber and energy have direct relation, when wavenumber will halve , energy will be halved.

3. The relationship between energy and frequency of the wave follows the equation:

[tex]E=h\times \nu[/tex]

where

E = energy

h = Planck's constant  

[tex]\nu[/tex] = frequency of the wave

Thus as frequency and energy have direct realation, when frequency will double , energy will double.
