The equation for photon energy, E , is

Chemistry

Sidana [21]2 years ago

The wavelength of a photon that has an energy of E = 3.69×10−19 J is 5.42 x 10⁻⁷ m.

<h3>What do you mean by wavelength?</h3>

The space between corresponding points (adjacent crests) in adjacent cycles is known as the wavelength () of a waveform signal that is sent in space or down a wire.

The wavelength can be calculated by the given formula

E = hc/λ

Where,  E is energy = 3.65 x 10⁻¹⁹ J

h is plank's constant = 6.626 x 10⁻³⁴ J.sec

c is speed of light = 2.9 × 10⁸ m/s

Putting the values in the formula

λ = (6.626 x 10⁻³⁴)(2.9 × 10⁸) / (3.65 x 10⁻¹⁹) = 5.42 x 10⁻⁷ m.

Thus, the wavelength, λ is 5.42 x 10⁻⁷ m.

Archy [21]

Answer: A)  polar molecule  

Explanation: Polar molecules are molecules which contain atoms of different electronegativities.

Non polar molecules are molecules which contains atoms of same electronegativities.

Water is a polar covalent molecule formed by unequal sharing of electrons. Oxygen being more electronegative tend to keep the electron pair towards itself thus generating a partial negative charge. The hydrogen acquire a partial positive charge thus resulting in a polar molecule.

The bent shape is due to repulsion between lone pairs and bond pairs of electrons.
