 f = 7.4 x 10²⁰s⁻¹

Explanation:

Given parameters:

wavelength of light = 405 x 10⁻⁹m or 405nm

Unknown:

Frequency of light = ?

Solution:

We can solve this problem using the wave equation:

                  V = f∧

where V is the velocity of light = 3 x 10⁸m/s

           f is the unknown frequency

           ∧ is the wavelength of light

          making f the subject:

                   f = \frac{V}{wavelength} = \frac{3 x 10[tex]^{8}}{405 x 10^{-9}}[/tex]

                   f = 7.4 x 10²⁰s⁻¹

How does temp affect the phase of a substance
notka56 [123]

Answer:

state of matter

Explanation:

so take water for example, water has a melting point and a boiling point right? So if it's below 0 degrees, then it's in its solid phase. If the temperature is above 0 degrees, then the water starts to melt into its liquid phase. Then when the temperature is above 100 degrees, water starts to boil and become its gas phase. This is the same for all substances. The only difference is different substances have different melting and boiling points so the numbers will be different depending on your substance. hope this helped!

One gram of alum, KAl(SO4)2.12H2O, contains 1.3 × 1021 Al atoms. How many oxygen atoms are contained in 1.0 g alum?
Roman55 [17]

From the chemical formula, 1 formula unit of KAl (SO4)2.12H2O encompasses 1 atom of Al = 4 * 2 atoms of O in KAl (SO4)2 + 12 atoms of O in 12H2O which is equal to 20 atoms of O.

So, if you have 1.3 × 10^21 Al atoms, you have 20 * 1.3 × 10^21 O atoms will now be equal to 2.6 * 10^22 atoms of O.
