Violet light has a frequency of 7.26 * 1014 hz and travels at a speed of 3.00 * 108 m/s. the wavelength of violet light, rounded to the nearest nanometer, is nm.

c=λν

3*10^8 m/s * 10^9 nm/m / 7.26*10^14 s^-1= λ

=413.22 nm

λ=413 nm

Answer : The wavelength of violet light is, 413 nm

Explanation :

Formula used :

where,

= frequency of violet light =

As we know that,

= wavelength of violet light

c = speed of light =

Now put all the given values in the above formula, we get:

conversion used :

Therefore, the wavelength of violet light is, 413 nm

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.

explanation:

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
