Irregular reflection : When a beam of light falls on rough, unpolished surfaces such as wood, paper etc. the light reflects in different directions.

All reflected light obeys the relationship that the angle of incidence equals the angle of reflection. When the surface of water is wind-blown and irregular, the rays of light are reflected in many directions. The law of reflection is still obeyed, but the incident rays.

Force is a push or a pull that changes or tends to change the state of rest or uniform motion of an object or changes the direction or shape of an object. It causes objects to accelerate. SI unit is Newton.

Five effects of force:

1. A force can move a stationary object.
2. A force can stop a moving object
3. A force can change the speed of a moving object.
4. A force can change the direction of a moving object.
5. A force can change the shape and size of an object.

Without friction we cannot walk around, walking will be a difficult task. Writing on a paper or a surface/area would be very difficult.Etc.

Eight planets and their special features:

1. Mercury➠ Mercury is hot, but not too hot for ice.
2. Venus➠Venus doesn’t have any moons, and we aren’t sure why.
3. Mars➠Mars had a thicker atmosphere in the past.
4. Jupiter➠ Jupiter is a great comet catcher.
5. Saturn➠No one knows how old Saturn’s rings are
6. Uranus➠ Uranus is more stormy than we thought.
7. Neptune➠ Neptune has supersonic winds.
8. Earth➠ You can see Earth’s magnetic field at work during light shows.

Electrolysis is applied in the various field. It is required for extraction and purification of metals. It is used as one of the commercial processes to produce hydrogen gas. It is also used to prevent the rusting of metals.

Answer 2

Answer:

when a parallel beam of light incident upon a surface is reflected on unparallely in different direction then it is called a regular reflection
