## Lecture on Space Basic

Subject: Physics | Topics:

General objective of this lecture is to present on Space Basic. A star (our sun) is part of a galaxy. A planet (earth) orbits a star. A moon (our moon) orbits a planet (earth). From the perspective of an Earthling, outer space is a zone that occurs about 100 kilometers above the planet, where there is no appreciable air to breathe or to scatter light. One light year is the distance travelled by light in a year. It takes light from the sun 8 minutes to get to the earth. It takes 4 light years for light to reach the nearest star (alpha centauri). It takes light 100,000 light years to get to the edge of our galaxy.

### Assignment on fundamental sciences

Fundamental sciences is the study of material things was treated as a single aspect of human thought and called natural philosophy. But as knowledge increased it was found necessary to divide the study of nature into two main branches. They are  two main fundamental sciences are- A. Physical sci.....

### Assignment on Refraction of Light

Reflection of Light The bouncing off of light or any wave at the face or boundary between two medium is called refraction.The figure above illustrates the regular reflection of a light ray. MM` represents the surface of a plane mirror. AO is the incident ray i.e. the direction in which light fall.....

### Experiment Study of Wein Bridge Oscillator

Prime objective of this case study is to experiment on Wein Bridge Oscillator. The oscillator is a circuit where a balanced bridge is used because feedback network is Wien Bridge oscillator. The aim of this experiment is to check the operation of the Wien Bridge. To explain this experiment here .....

### What is Wave

Wave is a form of disturbance which travels onward due to repeated periodic motion of the medium particles. Energy is transferred during wave motion. Types of wave Mechanical wave: This type of wave motion requires material medium to propagate. For example ripples on water surface, vibration of a.....

### Experiment Study of Class-C Tuned Power Amplifier

Primary objective of this case study is to experiment on Class-C Tuned Power Amplifier. Here focus on an amplifier that has tuned collector load and active device transistor operating at Class- C mode and observe the output voltage and current relationship at different harmonics. To experiment .....
