Below are the choices that can be found in the other sources:
A. diffraction
<span>B. refraction </span>
<span>C. reflection </span>
<span>D. transmission
</span>
The answer is diffraction. It means that <span>the process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge, typically accompanied by interference between the wave forms produced.</span>
When the image of a distant object is brought into focus of front of a person's retina, the defect is called: nearsightedness.
Solution :
1. Rayleigh scattering takes place when the particle size is smaller than the wavelength (λ).
2. Mie scattering takes place when particle size is nearly equal to the wavelength (λ).
3. Non-selective scatter takes place when particle size in greater than the wavelength (λ).
We have the sizes of different particles :
Smoke particles
Cloud droplets
Rain droplets

The temperature of the copper sample increases by
Explanation:
When energy is supplied to a substance, the temperature of the substance increases according to the equation:
where
is the increase in temperature
Q is the amount of energy supplied
m is the mass of the substance
is the specific heat capacity of the substance
For the sample of copper in this problem,
m = 538.0 g
Q = 8373 cal
Therefore, substituting we have:

Answer:
Without light, we can't see. So life would have been harder-much harder.
Explanation:
Our eyes take in light to see- in the darkness they take in as much light as possible, and when it's bright, they take in as little as possible. They do this by changing the size of the pupil.
If there is no light, people cannot see. So how would we know where we are going?
Here's how: we would evolve over time to use our other senses ( smell, taste, touch and hearing) better, like animals with bad eyesight.
Our senses of smell and hearing would play the most important role.
