## Walter Houser Brattain: Physicist

Subject: Physics | Topics:

Walter Houser Brattain, Physicist was born Feb. 10, 1902, Amoy, China. He was an American scientist who, along with John Bardeen and William B. Shockley, won the Nobel Prize for Physics in 1956 for his investigation of the properties of semiconductors—materials of which transistors are made—and for the development of the transistor. Brattain attended Whitman College in Walla Walla, Washington, where he studied with Benjamin H. Brown (physics) and Walter A. Bratton (mathematics). Brattain earned a bachelor’s degree from Whitman College in 1924, with a double major in physics and mathematics. He earned a Master of Arts from the University of Oregon in Eugene in 1926. Brattain earned a Ph.D. from the University of Minnesota, and in 1929 he became a research physicist for Bell Telephone Laboratories.

### 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 .....
