Explanation:
It is given that,
Refractive index of zircon, n = 1.923
The wavelength of visible light ranging from 380 nm to 760 nm in a vacuum.
Wavelength 1,
Wavelength 2,
We need to find the shortest and longest wavelength. For shortest wavelength,
For longest wavelength,
Hence, this is the required solution.
the correct answer is 1. Chemical energy is converted to mechanical and heat energy.
When the boy eats apple, the chemical energy of the apple first converted in the heat energy in the process of digestion, which maintains our body temperature, than the body of the boy converts the heat energy into mechanical energy.
Therefore the correct option is 1.
I think the answer is b Behaviors of the electrons help cause both the shininess and the conductivity of metals
The first step in problem solving is of
course, identifying the problem. How could you solve the problem if there is no
problem in the first place? When one gets to identify the problem, the next
step is gathering of information to know more about the problem. One needs to
get to know and examine the pros – the benefits – and con – the flaws – of the
problem well. After doing all the needed data gathering and possibly,
experimentation, when can start looking for the possible solutions of the
problem.
