Select the correct term to complete each sentence.

leva [86]

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.

think about items you or your family bought over the last week. what kind of packaging was around those items? How did you dispo

Sunny_sXe [5.5K]

Answer:

its not that hard, i mean its a question that you kinda have to answer yourself. its basically asking you to write down the items that your family brought over the last week. just think of the things that your parents or family brought home. then you have to tell them what packaging was around the items, for example, plastic. and then etc.

Hope that helps you!
