Question

Select the correct term to complete each sentence.

Answer 1

Answer: 1. halve

2. halve

3. double

Explanation:

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

$E=\frac{hc}{\lambda}$

E= energy

$\lambda$ = 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:

$E=h\times c\times \bar{\nu}$

E= energy

$\bar{\nu}$$\nubar$ = 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:

$E=h\times \nu$

where

E = energy

h = Planck's constant  

$\nu$ = frequency of the wave

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