The teal line of the hydrogen emission spectrum has a wavelength of 486.0 nm.486.0 nm. Calculate the energy of one photon of this light.

4.086 × 10⁻¹⁹ J

Explanation:

Step 1: Given and required data

Step 2: Convert "λ" to meters

We will use the conversion factor 1 m = 10⁹ nm.

486.0 nm × 1 m/10⁹ nm = 4.860 × 10⁻⁷ m

Step 3: Calculate the energy of one photon of this light

We will use the Planck-Einstein's relation.

E = h × c / λ

E = 6.626 × 10⁻³⁴ J.s × 2.997 × 10⁸ m/s / 4.860 × 10⁻⁷ m

E = 4.086 × 10⁻¹⁹ J

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.
