Line spectra from all regions of the electromagnetic spectrum, including the paschen series of infrared lines for hydrogen, are used by astronomers to identify elements present in the atmospheres of stars. calculate the wavelength of the photon emitted when the hydrogen atom undergoes a transition from n = 5 to n = 3. (r = 2.179 x 10-18 j r = 1.096776 x 10^7 m-1) a. 205.1 nm b. 384.6 nm c. 683.8 nm d. 1282 nm e. > 1500 nm

The correct answer is option D.

Explanation:

Using Rydberg's Equation for hydrogen atom:

Where,

= Wave number

= Wavelength of radiation

= Rydberg's Constant

= Higher energy level

= Lower energy level

We have:

()

The wavelength of the photon emitted when the hydrogen atom undergoes a transition from n = 5 to n = 3 is 1282 nm.

your answer would be a. 12.5 kg

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.
