Answer:
Doing science could be defined as carrying out scientific processes, like the scientific method, to add to science's body of knowledge.
Hey there,
Density = Mass/Valume
D= 3.1/0.35
D= 8.86 g/cm3
The orbital with the lowest energy is 3s.
Answer it ur self if u have internet
Explanation:
(a)
Critical angle is the angle at the angle of refraction is 90°. After the critical angle, no refraction takes place.
Using Snell's law as:
Where,
is the angle of incidence
is the angle of refraction = 90°
is the refractive index of the refraction medium
is the refractive index of the incidence medium
Thus,
The formula for the calculation of critical angle is:
Where,
is the critical angle
(b)
No it cannot occur. It only occur when the light ray bends away from the normal which means that when it travels from denser to rarer medium.
