I don't know but i would like to!
No, the longitudinal wave can't be polarised. Because polarisation means lack of symmetry. But longitudinal waves are symmetrical from all the sides of vision. This is because their plane of propagation and vibration is same. this wave loks same from all the sides.
Sound waves, which are mechanical energy, travel in all directions because of diffraction. Diffraction can be thought of as the "bending" of sound waves. To find a more detailed answer to this question, go to the related link listed below. It answers the question perfectly.
Megaphones work by capturing sound waves from a person's voice and then amplifying and directing those sound waves in a specific direction. The shape of the megaphone helps to focus the sound waves and make them louder and clearer for listeners.
When both sides are pulling with equal force, the object is either moving at a constant speed or it is stationary (not moving) :)
The ultimate source for the earth is sunlight. Due to the sunlight the water in the ocean surface get heat the water in the surface layers which makes the lighter and moves as hot waves towards the cold regions and cold water from the bottom or sides move up. Convection movements takes place and thus ocean waves are formed. Thus solar energy changes to mechanical energy in precise kinetic energy. Hope this will clarify the doubt
A sea arch is formed by erosion, not deposition. It is created by the continuous action of waves eroding the rock from both sides of a headland, eventually forming an arch.
peninsulas are formed when waves start hitting a section of rock on the coastline that is not as easilly eroded as the rock around it. Over time it starts to stick out as a headland and if that process continues for enough years, the waves hitting the headland will start to curve around the sides and begin eroding the softer rock behind.
A headland
if you are on a headland where is the water
Sea arch
Headland or peninsular.
A sea arch is formed primarily by erosion. As waves erode the coastline, they create a hole or cave in a headland. Over time, this continual erosion causes the cave to expand from both sides until it forms an arch.
When two sea caves on opposite sides of a headland unite, they form an arch. Over time, continued erosion can cause the arch to collapse, leaving behind a stack. Subsequent erosion can erode the stack to form a sea stack.
A piece of land that juts out into the sea is called a peninsula. Peninsulas are surrounded by water on three sides and are connected to the mainland by a narrow strip of land. Examples include the Florida peninsula in the United States and the Iberian peninsula in Europe.
The adjoining sides are not parallel, they are perpendicular; forming right angles.
I think a peninsula is when the entire landmass sticks into the ocean on 3 sides, and a headland is when a smaller portion of shore sticks out into the ocean.
Headland,Sea Cave, Sea Arch, Sea stack,and wave-cut cliff. EXAMPLE WITH SEA ARCH AND SEA STACK: A sea arch is formed when two caves on opposite sides of a headland join. The sea arch collapses when the waves & weathered sediment (rock particles),hit it continuously in which a sea stack is formed. the sea arch is then .eroded and deposited in a new place.
