Answer:
The answer is "
"
Explanation:
Z=2, so the equation is 
Calculate the value for E when:
n=2 and n=9
The energy is the difference in transformation, name the energy delta E Deduct these two energies
In this transition, the wavelength of the photon emitted is:
Answer: 77 degrees
Explanation:
According to the Law of Reflection, when a ray of light strikes a surface, the angle of this ray (incident ray) with respect to the normal of the surface is equal to the angle that forms the reflected ray with the same normal of the surface.
In other words:
Both the incident ray and the reflected ray and the normal to the surface are in the same plane, in addition, the angle of the incident ray is equal to the angle of the reflected ray.
In this context, if the angle of incidence is 77 degrees, the angle of reflection is 77 degrees, as well.
Hey all you can do is type the question on the internet and click on the one that has the same title as yours and the answers will be there im taking physics and i do that all the answers will be there
Answer:
Explanation:
wavelength of light = 4 x 10⁻⁷ m
frequency = velocity in air / 4 x 10⁻⁷
= 3 x 10⁸ / 4 x 10⁻⁷
= .75 x 10¹⁵ Hz
= 75 x 10¹³ Hz.
Wave length = 4 x 10⁻⁷ m
= 400 x 10⁻⁹m
400 nm
colour of light having this wavelength in air is violet .
