sergejj [24]

When you see a long dash joining two elements in the structural formula of a chemical molecule you can assume that the chemical bonds in the compound are simple bonds.

In the representation of chemical molecules long dashes are used to represent simple bonds since these bonds are longer than double and triple bonds, which are represented by = and ≡ respectively.

The equation for photon energy, E, is E=hcλ where h = 6.626×10−34 J⋅s (Planck's constant) and c = 2.99×108 m/s (the speed of lig
masya89 [10]

Answer:

9.133×10^-6 m

Explanation:

A photon is the smallest discrete amount or quantum of electromagnetic radiation. It is the basic unit of all light. Photons are always in motion and, in a vacuum, travel at a constant speed to all observers of 3 x 10^8 m/s.

From the question, the following details were supplied;

Energy of the photon (E) = 4.61×10^−19 J

Speed of light (c) = 2.99×10^8 m/s

Plank's constant (h) = 6.626×10^−34 J⋅s

Wavelength of the photon (λ)= ??? The unknown

From

E=hc/λ

λ= hc/E

Substituting values

λ= 6.626×10^−34 × 2.99×10^8/ 4.61×10^−19

λ= 91.33×10^-7 m

λ= 9.133×10^-6 m
