Hace 3 días · Surface waves in water showing water ripples. In physics, mathematics, engineering, and related fields, a wave is a propagating dynamic disturbance (change from equilibrium) of one or more quantities. Periodic waves oscillate repeatedly about an equilibrium (resting) value at some frequency.
Hace 2 días · Investigating optics – specifically light refraction – Hooke inferred a wave theory of light. His is the first-recorded hypothesis of the cause of the expansion of matter by heat, of air's composition by small particles in constant motion that thus generate its pressure, and of heat as energy.
Hace 3 días · General relativity. Gravitational waves are waves of the intensity of gravity that are generated by the accelerated masses of binary stars and other motions of gravitating masses, and propagate as waves outward from their source at the speed of light.
Hace 1 día · Snell's law, also known as the law of refraction, is a law stating the relationship between the angles of incidence and refraction, when referring to light passing from one medium to another medium such as air to water, glass to air, etc.
Hace 5 días · Determine the refractive index of a ray of light moving from water to glass. (3mks) Light is incident on an air-glass boundary at an angle of incidence of 40 0. If the refractive index of the glass is 1.7, determine the angle of refraction. (3mk) Fig (i) and (ii) show refraction of light at air-water interface.
Hace 3 días · The equations of motion of kinematics describe the most fundamental concepts of motion of an object. These equations govern the motion of an object in 1D, 2D and 3D. They can easily be used to calculate expressions such as the position, velocity, or acceleration of an object at various times. Do you know the speed of the world fastest human?
Hace 5 días · Learn how to find and shoot the right mix of motion blur and stopped action for flowing water photography. We’ll mention exposure, shutter speeds, and more.
