Answer 1

Answer:

1. Hydrocarbon = A hydrocarbon is an organic chemical compound exclusively of hydrogen and atoms.

2. Allotropes / Allotropy= The existence of an element in two or more chemically similar but physically different form is called allotropy and different forms are called allotropes.

3. Carbon footprint = A carbon footprint is the amount of greenhouse gases produced by human activity.

4. Frequency= Number of oscillation made by a wave in one second is known as Frequency.

5. Wave length = In physics, the distance between successive creates of a wave is called Wave length.

6. polarization of light= The process which causes light waves to vibrate in a single plane is called polarization of light.

7 .Amplitude= It is the maximum extend of vibration measured from the position of equilibrium.

8 . Loudness= The loudness of a sound increases with the amplitude of wave.

9 . Incident Ray= Light which falls on the mirror surface is called incident ray.

10 . Angle of reflection= The angle between reflected ray and the normal is known as angle of reflection.

11 . Normal = The perpendicular drawn to the reflecting surface is called Normal at that point.

12 . Waves = Wave involve the transport of energy without the transport of matter.

13 . Sound = Vibration that travel through the air or another medium is known as sound.
