What is the wavelength (in nanometers) of a photon emitted during a transition from ni = 7 to nf = 3 state in the H atom?

Explanation:

To determine the wavelength; let's first calculate the energy (E) change of the transition by using the Rydberg constant

Now; to calculate the wavelength by using the formula:

To nanometers; we have:

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
