In still water. do waves travel outward in all directions at the same speed? o yes o no

Yes, in still water, waves typically travel outward in all directions at the same speed. The speed of a wave is determined by the properties of the medium, which, in this case, is water. When a wave is generated, for example by a stone dropped into a still pond, the ripples or waves will spread out evenly in all directions from the point of disturbance, assuming the water depth and other environmental conditions are uniform in all directions.

It's important to distinguish between waves in deep water and shallow water. In deep water, where the depth is greater than half the wavelength of the waves, the speed of wave propagation is primarily dependent on the wavelength. For surface waves on water, gravity is the restoring force that allows the waves to propagate, and larger wavelengths will therefore travel faster.

In shallow water, where the depth is less than one twentieth of the wavelength, the speed of the wave is determined by the depth of the water. In this case, all waves travel at the same speed if the water depth is consistent, because it's the water depth rather than the wavelength that controls the speed.

Another interesting point is that waves do not transfer the water itself over a distance. Instead, the energy of the wave moves through the water, causing the water particles to move in a circular motion. As a wave passes, particles of water return to their original position, but the energy of the wave has moved on, transferring to other water particles. This is why we see the wave moving outward in all directions from the point where something disturbed the water, such as a stone being dropped
