The transmission of light waves is usually done through cornea of the eyes, then move through another opening which is regarded as pupil before it will get to the retina.
- Light waves can be regarded as moving energy which contains microscopic particles known as photons.
- The vision of the eye can be completed through the light wave passing through the components of the eyes and this process goes thus;
- Light will move through the (cornea) which is situated at the front area of the eyes into lens.
- Then both the cornea and the lens give room for the focusing of the light rays to the retina which is situated at the back of the eye .
- Then through the help of the cells in the retina, the light will be absorbed and then be converted to electrochemical impulses and then transfer it to the brain as well as optic nerve.
Therefore, light wave are form of tiny microscopic particles.

The answer is b because ya its b
Answer:
0.9432 m/s
Explanation:
We are given;
Mass of swimmer;m_s = 64.38 kg
Mass of log; m_l = 237 kg
Velocity of swimmer; v_s = 3.472 m/s
Now, if we consider the first log and the swimmer as our system, then the force between the swimmer and the log and the log and the swimmer are internal forces. Thus, there are no external forces and therefore momentum must be conserved.
So;
Initial momentum = final momentum
m_l × v_l = m_s × v_s
Where v_l is speed of the log relative to water
Making v_l the subject, we have;
v_l = (m_s × v_s)/m_l
Plugging in the relevant values, we have;
v_l = (64.38 × 3.472)/237
v_l = 0.9432 m/s
A geocentric system is a part of the astronomical theory which describes the universe. Meaning that it puts the Earth in the CENTER of the universe as a point of view for other objects surrounding it.
Answer: the amphoteric line, mental- nonmetal line, metalloid line, staircase, semimetal line. it can be called any of these names
