Question
Formulate a hypothesis regarding how the frequency of a wave affects its wavelength, providing scientific reasoning to support your hypothesis.
Solution
Hypothesis: The frequency of a wave is inversely proportional to its wavelength.
Scientific Reasoning:
-
Understanding the basics: A wave is a disturbance that transfers energy from one place to another. It is characterized by properties such as amplitude, frequency, wavelength, and speed. Frequency refers to the number of complete wave cycles per second, while wavelength refers to the distance between two consecutive points in a wave that are in the same phase.
-
The relationship between speed, frequency, and wavelength: The speed of a wave is determined by the medium through which it travels and is given by the product of its frequency and wavelength (v = fλ, where v is speed, f is frequency, and λ is wavelength).
-
Inverse relationship: If the speed of a wave is constant (as it is when a wave travels through a single uniform medium), an increase in frequency will result in a decrease in wavelength, and vice versa. This is because frequency and wavelength are inversely proportional to each other (f = v/λ), assuming the speed is constant.
-
Real-world examples: This relationship is observed in various types of waves. For instance, in the electromagnetic spectrum, radio waves have a lower frequency and longer wavelength, while gamma rays have a higher frequency and shorter wavelength.
Therefore, based on the scientific understanding of wave properties, we can hypothesize that the frequency of a wave affects its wavelength in such a way that an increase in frequency will result in a decrease in wavelength, assuming the speed of the wave remains constant.
