Answer:
Ok let's do this how are you❤️
An environmental scientist studies the environment - you can see that in the beginning of the sentence :)
The wavelength of light : 4.14 x 10⁻⁵ m
<h3>Further explanation
</h3>
Radiation energy is absorbed by photons
The energy in one photon can be formulated as

Where
h = Planck's constant (6,626.10⁻³⁴ Js)
f = Frequency of electromagnetic waves
The energy of the light = 4.8 x 10⁻²¹ J
The wavelength of light :

.54 km to dm is 5,400 decimeters. Hope this helps, have a BLESSED day! :-)
It’s all based on you but yours could be anything hard you went through and how you overcame it. Also say how it made you the person you are today
