It's not supposed to change. If the cross-sectional area does change through a bend,
then the pipe is said to be "kinked". The bend is regarded as poorly done, and if the
kink is deep enough, the section of pipe including the bend may have to be replaced.
Bending a wire can change its resistance due to changes in its length and cross-sectional area. However, resistivity, which is an intrinsic property of the material, remains constant regardless of bending.
Refraction is the bending of light when it passes through a lens. This bending occurs due to the change in speed of light as it moves from one medium (such as air) to another (such as glass). The degree of bending depends on the refractive index of the materials involved.
Refraction involves the bending of waves as they pass from one medium to another due to a change in the wave's speed. Diffraction, on the other hand, involves the bending of waves around obstacles or through openings. Both phenomena are important in understanding how waves behave in different situations.
Refraction is the bending of light waves when they pass through another substance. This phenomenon occurs due to a change in the speed of light as it travels from one medium to another, causing the light waves to change direction.
The bending of light rays as they pass through different materials is known as refraction. This occurs due to a change in the speed of light as it moves from one medium to another, causing the light ray to change direction. The amount of bending depends on the difference in the refractive indices of the two materials.
Scientists use the term "refraction" to describe the bending of light as it passes through different mediums, such as air, water, or glass. This bending occurs due to the change in the speed of light as it travels through substances with varying densities.
The process of light bending is called refraction. This occurs when light passes through different mediums, such as air to water, causing the light to change direction.
No, light bending through a prism is an example of refraction, not reflection. Refraction occurs when light passes through a medium with a different refractive index, causing the light to change direction. Reflection, on the other hand, occurs when light bounces off a surface.
The bending of waves due to a change in speed is called refraction. This occurs when waves pass through different mediums with varying densities, causing the wave to change direction.
No, bending a paper clip is a physical change because the material of the paper clip remains the same before and after bending. Chemical changes involve a change in the chemical composition of a substance.
Sound bending occurs when there are changes in the medium through which the sound travels because the speed of sound varies depending on the properties of the medium. When sound waves encounter a change in medium, such as going from air to water or passing through different temperatures, they can bend or change direction due to the difference in speed. This bending is known as refraction and can cause sound to be heard differently than expected.
The bending of light is called refraction. This occurs when light travels through different mediums, such as air and water, causing the light ray to change its direction.
