Answer:

The frequency of this light is $6.98\times 10^{14} s^{-1}$ .

Explanation:

Wavelength of the light = $\lambda = 430 nm=4.30\times 10^{-7} m$

Speed of the light = c = $= 3\times 10^8 m/s$

Frequency of the light = $\nu$

$\nu =\frac{c}{\lambda }$

$\nu =\frac{3\times 10^8 m/s}{4.30\times 10^{-7} m}=6.98\times 10^{14} s^{-1}$

The frequency of this light is $6.98\times 10^{14} s^{-1}$ .

Do you relizes how many activities lead to global warming? When gas is burned in a car, it produces carbon dioxide (a green house gas). The carbon dioxide then floats up towards the atmosphere and becomes part of the atmosphere. This then causes the heat from the sun to get trapped, bouncing from the atmosphere to the earth. The sun will never stop producing heat which will only lead to the world getting hotter as each decade goes by.

Hope this helps you!

How many grams are in 44.8 liters of nitrogen gas, n2?<br> a) 56g<br> b) 27g<br> c) 36g<br> d) 112g

kkurt [141]

a) 56g

<h3>Calculation:</h3>

At STP,

22.4 L of N₂ = 1 mol

We have given 44.8 L of N₂, therefore,

44.8 L of N₂ = $\frac{44.8}{22.4}$
