Thanks I see it now @kuruman ! Is the reason why they used radians instead of degrees in the arc length formula is because radians is a ratio of the length while degrees is not.kuruman said:##AB=2R\sin30^o.## Do you see why? Hint: Draw a perpendicular from the center to the base AB. It splits AB into two equal parts. What is the length of each part?
Yes, both are dimensionless in the usual dimensionality system; they just have different units.Callumnc1 said:
The concept of finding time difference between two arriving wave fronts involves measuring the difference in time it takes for two wave fronts to reach a given point. This can be used to determine the distance between the two wave sources or to calculate the speed of the wave.
Finding time difference between two arriving wave fronts is important in a variety of fields, including physics, engineering, and astronomy. It can help us understand the behavior of waves and their sources, and can also be used to make precise measurements and calculations.
There are several factors that can affect the accuracy of finding time difference between two arriving wave fronts. These include the precision of the measuring instruments, the distance between the wave sources, and any external factors that may influence the speed of the waves, such as temperature or interference.
There are several methods that can be used to find the time difference between two arriving wave fronts. These include using a stopwatch or timer, using specialized equipment such as oscilloscopes or interferometers, and using mathematical calculations based on the known speed of the wave.
The concept of finding time difference between two arriving wave fronts has many practical applications. It can be used in navigation systems, such as GPS, to determine location and calculate travel time. It can also be used in seismology to study earthquakes and in sonar technology for underwater mapping and communication.
