An electromagnetic wave having a frequency of 1.33x1017 Hz, what is its wavelength?

Chemistry
1 answer:
Dennis_Churaev [7]3 years ago

Its wavelength : 2.31 x 10⁻⁹ m

<h3>Further explanation </h3>

Radiation energy is absorbed by photons

The energy in one photon can be formulated as

\large{\boxed{\bold{E\:=\:h\:.\:f}}}

Where

h = Planck's constant (6,626.10⁻³⁴ Js)

f = Frequency of electromagnetic waves

f = c / λ

c = speed of light

= 3.10⁸

λ = wavelength

Frequency of electromagnetic waves  : 1.33 x 10¹⁷ Hz

the wavelength :

\tt \lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3.10^8}{1.3\times 10^{17}}=2.31\times 10^{-9}

Answer:

N=2

H=6

Explanation:

1.Balance a chemical equation in terms of moles.

2.Use the balanced equation to construct conversion factors in terms of moles.

3.Calculate moles of one substance from moles of another substance using a balanced chemical equation.

The law of conservation of matter says that matter cannot be created or destroyed. In chemical equations, the number of atoms of each element in the reactants must be the same as the number of atoms of each element in the products.

(P.s it could also be where you have to solve it in which you have to simplify it first then solve it.) like adding them all up.

Hope this is the answer. :)

Which mineral(s) might you be examining if you place some hydrochloric (hcl) acid on a sample and it fizzes?
makvit [3.9K]
The minerals that one might be examining if you place some hydrochloric acid on a sample and it fizzes are Calcite and Dolomite.
Calcite and dolomite are very similar minerals. Both have the same hardness, the same rhombohedral cleavage, and are found in identical geologic settings. The best way to tell one from the other is the acid test; A drop of 1 M HCl on calcite produces an instant , obvious Fizz; a drop on dolomite produces slow or no obvious bubbling.

What patterns in the rock layer fossils helped you identify an extinction?
Dafna11 [192]
Often, the rock layers bookending the mass extinction are noticeably different in their compositions. These changes in the rocks show the effects of environmental disturbances that triggered the mass extinction and sometimes hint at the catastrophic cause of the extinction
