Radiation from a cesium-133 atom completes \(9,192,631,770\) cycles each second. How long does it take for this radiation to complete \(1.5\) million cycles?

Short Answer

Expert verified
It takes about 0.000163 seconds.

Step by step solution

01

Define the Rate of Cycles

The radiation from a cesium-133 atom completes \(9,192,631,770\) cycles per second. This rate will be used to find out how much time it takes for the radiation to complete a different number of cycles.
02

Set Up the Equation

To find the time taken to complete 1.5 million cycles, set up the equation based on the relationship: \( \text{Time} = \frac{\text{Number of cycles}}{\text{Cycles per second}} \).
03

Calculate the Time

Substitute the given values into the equation: \( \text{Time} = \frac{1,500,000}{9,192,631,770} \).
04

Compute the Result

Perform the division: \( \text{Time} \approx \frac{1,500,000}{9,192,631,770} \approx 0.000163205\) seconds.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Cesium-133 Atom
The cesium-133 atom is fundamental in the field of timekeeping. It is the atom used in atomic clocks, which are the most accurate timekeeping devices available today. Atomic clocks work on the principle that cesium-133 atoms vibrate at a very consistent frequency. These vibrations form the basis for the second, the basic unit of time in the International System of Units (SI). The reason cesium-133 is preferred is because of its stable frequency emission, making it perfect for precise measurements. These clocks can help in various applications, from GPS technology to scientific research where accurate time measurement is essential.
Time Calculation
Time calculation is crucial in understanding how many events occur over a given period. In the context of the original exercise, it involves determining how long it takes for a specified number of atomic cycles to complete. To calculate time, the relationship between the number of cycles and their frequency is vital. The formula used is:
  • Time = \(\frac{\text{Number of cycles}}{\text{Cycles per second}}\)
This formula helps convert a series of cyclic events into a timeframe, making it easier to understand the duration required for any process based on cycle data.
Cycle Rate
The cycle rate refers to how often a repeating event occurs and is usually measured in cycles per second, known as Hertz (Hz). In the context of cesium-133, the cycle rate is essential in defining the atom's vibrational frequency. This frequency is used to measure time with high precision and is defined as \(9,192,631,770\) Hertz for cesium-133. A higher cycle rate indicates that events occur more frequently in a given period. Understanding the cycle rate can help in numerous scientific and practical tasks, such as assessing time intervals or syncing activities to a precise temporal schedule.
Physics Problem Solving
Physics problem-solving is about applying known physical principles to find unknown quantities. In problems like calculating time from a given cycle rate, the process involves setting up a clear mathematical model and using equations correctly. The solution is derived by understanding the relationship between the different components, such as number of cycles and cycle rate, which are given in the form of data.
  • Identify the Known and Unknowns: Understand what information is provided and what needs to be solved.
  • Apply Relevant Formulas: Use appropriate mathematical relations, like cycle formulas, to link knowns to unknowns.
  • Perform Calculations: Substitute values into the formula and carry out arithmetic operations.
This structured approach helps break down complex problems into manageable steps, leading to clear and precise solutions.

Give several examples of how physics applies to chemistry, meteorology, and biology. A Cricket Thermometer All chemical reactions, whether organic or inorganic, proceed at a rate that depends on temperature - the higher the temperature, the higher the rate of reaction. This can be explained in terms of molecules moving with increased energy as the temperature is increased and colliding with other molecules more frequently. In the case of organic reactions, the result is that metabolic processes speed up with increasing temperature. An increased or decreased metabolic rate can manifest itself in a number of ways. For example, a cricket trying to attract a mate chirps at a rate that depends on the overall rate of its metabolism. As a result, the chirping rate of crickets depends directly on temperature. In fact, some people even use a pet cricket as a thermometer. The cricket that is most accurate as a thermometer is the snowy tree cricket (Oecanthus fultoni Walker). Its rate of chirping is described by the following equation: $$ \begin{aligned} N &=\text { number of chirps in } 7.0 \text { seconds } \\ &=T-5.0 \end{aligned} $$ In this expression, \(T\) is the temperature in degrees Celsius.
