Is the velocity of water waves created in a container affected by the temperature of water. How?
Actually if you look at the phase velocity, [itex]c[/itex], for shallow water waves:Bobbywhy said:Surface waves on a fluid such as water do not obey the same laws that govern sound waves in water, so it’s not correct to assume they are affected by the same variables, in this case, temperature.
In this Wiki entry there is no mention of temperature affecting the phase velocity (also called “celerity” or “phase speed”):

The linear dispersion relation is usually understood for its behavior in two limits: In the limit of long waves (shallow water waves), the phase speed is affected only by depth, so that all waves propagate at the same speed. For the opposite limit (deep water waves), the wavelength matters but not the depth, and the waves become dispersive.Bobbywhy said:According to linear theory for waves forced by gravity, the phase velocity depends on the wavelength and the water depth. For a fixed water depth, long waves (with large wavelength) propagate faster than shorter waves.
In the case that depth matters (shallow water waves), then one might suppose that the temperature affects the phase speed through the (surely microscopic) change in depth, as suggested in posts three and eight.The phase velocity of an approximately sinusoidal wave is proportional to the square root of the wavelength. These are the waves described in the five examples given in post number five on March tenth that showed no effect of temperature change on phase velocity.
The speed of a wave in water is directly proportional to the temperature of the water. As temperature increases, the speed of the wave also increases. This is because warmer water molecules have more energy and can vibrate faster, causing the wave to travel faster.
As temperature increases, the wavelength of a wave in water decreases. This is because the speed of the wave increases, but its frequency remains constant. This results in a shorter wavelength.
Sound waves are a type of longitudinal wave that travels through the vibration of particles in a medium. In warmer water, the particles are more spread out due to increased energy, allowing sound waves to travel faster and more efficiently.
Yes, temperature changes can affect the direction of waves in water. This is because changes in temperature cause changes in the density of the water, which can lead to changes in the refraction of waves. Refraction is the bending of waves as they pass through different mediums, and changes in direction can occur when the speed of the wave changes due to temperature changes.
The amplitude of a wave in water is not affected by temperature. Amplitude is determined by the amount of energy that the wave carries, which is not affected by temperature. However, changes in temperature can affect the height of waves, which is a measure of their amplitude. This is because changes in temperature can cause changes in wind patterns, which can result in larger or smaller waves.
