Answer:

Energy of a single photon with the given wavelength is E=3.32\times 10^{-19}\ J

Explanation:

It is given that,  

The wavelength of yellow light,  \lambda=6\times 10^{-7}\ m

The equation that gives the relationship between the energy and the frequency of the wave is called Plank's equation. Mathematically, it can be written as :

E=h\nu

where \nu is the frequency of the wave and \nu=\dfrac{c}{\lambda}

h is Planck's constant

So, E=\dfrac{hc}{\lambda}

E=\dfrac{6.62\times 10^{-34}\ J-s\times 3\times 10^8\ m/s}{6\times 10^{-7}\ m}

E=3.32\times 10^{-19}\ J

So, the energy of photon is E=3.32\times 10^{-19}\ J

Determine why people who live in warm areas have a longer periods of allergic reactions to pollen then people who live in colder
astra-53 [7]

Answer:

This happens because pollination processes are increased over time, with time prevailing in the environment and in the air, and people with time hypersensitivity are more widespread over time.

Explanation:

Many scientists investigate these situations and mainly affect people at the respiratory level since pollen is inhaled, generating possible edema and bronchoconstrictions.

Other researchers also relate it to environmental pollution since it increases or extends the heat periods throughout the year, so this event is aggravated in patients with asthma and allergies, since the pollution has a direct effect on the airways.

Many particles suspended in the air by pollination and contamination are the cause of inflammation and bronchial hyperreactivity in patients with chronic pathologies. Substances like nitrogen oxides, sulfur dioxide, carbon monoxide and ozone promote the production of symptoms and exacerbations in children with asthma.
