Violet light has a wavelength of 422 nm, how much energy is found in this photon of violet light?
pashok25 [27]

Answer:

3.025eV

Explanation:

Energy of a photon is given by

E=hν

Where h is the Planck's constant

And ν represents the frequency of the photon .

Now for violet light wavelength λ=410nm= 410x10^-9m

By using the formula ν=c/λ

where c represents speed of light I.e 3 x 10^8 m/s

Calculating energy of violet photon we have

E=hc/λ

h=6.626 x 10^-34 J.s

On inserting the value in the formula , we get

E= 4.848 x 10^-19 Joules

To convert it into electron volts we need to divide it by 1.602 x10^-19.

The final result what we have is E=3.026eV.

Note: the result calculated is according to the above value . result may vary according to the values taken .

An aluminum block has a density of 2.70 g/mL. If the mass of the block is 24.60 g, find the volume of the substance.
harina [27]

Volume of a substance can be determined by dividing mass of the substance by its density.

That can be mathematical shown as:

Density=Mass/Volume

So, Volume=Mass/Density

Here mass of the substance given as 24.60 g

Whereas density of the substance is 2.70 g/mL

So,

Volume=Mass/Density

=24.6/2.7

=9.1 mL

So volume of the substance is 9.1 mL.
