Physics Tonic For SSC Exams
Dear Sehpaathians,
General awareness has always been taken at the lighter side by many of the candidates not realizing that how major it can be in SSC Exams. General awareness is not something you can expect to master in a day. But from an exam point of view, if you spend time consistently, you can perform well in it in relatively less time as compared to Quantitative Aptitude and Reasoning section. So, keeping the upcoming Railway & SSC Exams in mind, below is a Physics tonic and we assure you that this will be very useful to give your preparation a proper direction.
The Physics Tonic includes all the Physics topics you should be aware of for the upcoming Railway & SSC Exams.
Here is a small Preview
Echo: The repetition of sound due to reflection of sound waves is called an echo.
Intensity: It is defined as amount of energy passing normally per unit area held around that point per source unit time.
Pitch: The sensation of a frequency is commonly referred to as the pitch of a sound.
Sonar: It stands for sound navigation and ranging. It is used to measure the depth of a sea, to locate the enemy submarines and shipwrecks.
Doppler’s Effect : If there is a relative motion between source of sound and observer, the apparent frequency of sound heard by the observer is different from the actual frequency of sound emitted by the source.
