Title: Speed/Frequency/Wavelength Worksheet
소개:
In order to understand the concepts of speed, frequency, and wavelength, it is important to explore their definitions and how they are related to each other. This worksheet will provide a comprehensive overview of these concepts and use practical examples to further clarify their relationship.
나. Speed:
1. Definition:
The speed of an object refers to how fast it is moving. It is calculated by dividing the distance the object travels by the time taken to travel that distance.
2. Formula:
Speed = Distance / Time
3. Example:
Consider a car that travels a distance of 100 kilometers in 2 hours. To find its speed, divide the distance by the time:
Speed = 100 km / 2 hours = 50 km/h
II. Frequency:
1. Definition:
Frequency is the number of occurrences of a repeating event per unit of time. It is commonly used in physics to describe the number of waves passing through a given point in a second.
2. Formula:
Frequency = Number of Occurrences / Time
3. Example:
Imagine a water wave that passes through a buoy 10 times in 1 minute. We can calculate its frequency by dividing the number of occurrences by the time:
Frequency = 10 waves / 1 minute = 10 waves/minute
III. 파장:
1. Definition:
Wavelength refers to the distance between two corresponding points on a wave, such as the distance between two successive crests or troughs.
2. Formula:
Wavelength = Speed / Frequency
3. Example:
Suppose a wave is traveling at a speed of 300 meters per second with a frequency of 50 hertz. To find its wavelength, divide the speed by the frequency:
Wavelength = 300 m/s / 50 Hz = 6 meters
결론:
Understanding the concepts of speed, frequency, and wavelength is crucial for grasping various scientific phenomena, including waves and motion. By using the provided definitions, formulas, and practical examples, we hope this worksheet has successfully clarified and illustrated the relationship between these concepts.
