When a wave crosses a boundary between a thin and a thick rope, its frequency changes, but its wavelength and speed do not. True or false
I think the answer is True
nope
the frequency does not change. The speed of the wave changes so the length changes.
There is no place to store leftover crests and troughs if you try to get five out one end per second while putting four in the other end
False. When a wave crosses a boundary between a thin and a thick rope, its wavelength changes, but its frequency and speed remain constant. Just like when I try to squeeze into skinny jeans, the wavelength gets shorter in the thicker rope, but the frequency stays the same because I'm not compromising on my clownish speed!
The statement is False.
When a wave crosses a boundary between media with different properties, such as a thin and a thick rope, the frequency of the wave remains constant. However, the wavelength and wave speed can change.
According to the principle of conservation of energy, since the frequency remains constant, the wave speed must change when crossing the boundary. This change in wave speed causes a change in wavelength. The wavelength can vary depending on the change in properties of the media, such as the density and tension of the ropes.
Therefore, the frequency remains the same, but the wavelength and speed of the wave can change when it crosses the boundary.
The answer is False.
When a wave crosses a boundary between two different mediums, such as a thin and a thick rope, all three fundamental properties of the wave can be affected - wavelength, frequency, and speed. Let's break it down:
1. Frequency: The frequency of a wave is the number of complete cycles it completes in one second. When a wave crosses a boundary, the frequency remains unchanged. This means that the number of complete oscillations per unit time remains the same.
2. Wavelength: The wavelength of a wave is the distance between two adjacent peaks (or troughs) of the wave. When a wave crosses a boundary, the wavelength can change. In general, when waves travel from one medium to another, their wavelength can either increase or decrease, depending on the properties of the two mediums involved.
3. Speed: The speed of a wave is the rate at which it travels through a medium. When a wave crosses a boundary, the speed can also change. In different mediums, waves typically have different speeds due to variations in their mechanical properties, such as density and tension.
Therefore, in the context of crossing a boundary between a thin and a thick rope, the frequency may remain constant, but the wavelength and speed of the wave can be altered.
