Occurs when the plasma membrane surrounds a large substance inside the cell and moves it outside the cell?
exocytosis
Occurs when a wave bends as it crosses a boundary?
Refraction is the phenomenon in which a wave changes direction as it moves from one medium to another, caused by a change in its speed due to changing mediums. This bending of the wave occurs because the wave changes speed at different points along the boundary between the two mediums.
What is the bending of a wave at the boundry between two media called?
The bending of a wave at the boundary between two media is called refraction. This occurs when the wave changes speed as it moves from one medium to another, causing it to change direction.
The speed of a sound wave depends on properties of the medium occurs when a sound wave moves from one medium into another in which its speed is different?
Yes, the speed of a sound wave changes when it moves from one medium to another due to differences in the properties of the two mediums, such as density and elasticity. This change can result in phenomena like refraction or reflection of the sound wave at the boundary between the two mediums.
What do you call it when liquid moves through a porous substance?
That process is called infiltration. It occurs when liquid, such as water, seeps through porous materials like soil or rocks due to gravity or pressure differences.
What is it called when a wave changes direction as it passes from one substance to another at an angle?
It is called refraction. Refraction occurs due to the change in speed of the wave as it moves from one medium to another, causing the wave to bend.
What occurs when a substance moves from liquid to gas?
This change of phase is called vaporization and is a physical phenomenon; the chemical nature of the molecules was not changed.
What is a change in direction of a wave as it passes from one medium to another?
Refraction is the change in direction of a wave as it passes from one medium to another. This change occurs because the wave changes speed when it moves from one medium to another, causing it to bend.
Does frequncy of sound waves chance as it moves from on e substance to another if so what difference it makes for example from air to vacuum to water to solid materials?
The frequency of sound waves does not change in moving from one substance to another. Remember that vacuum is not a substance, but a lack of substance. Sound can't exist there.
What happens when a light ray moves from one substance to another?
When a light ray moves from one substance to another, it can undergo refraction, reflection, or absorption. Refraction occurs when the light ray changes speed and direction as it enters a new medium. Reflection happens when the light ray bounces off the surface between the two substances. Absorption occurs when the light ray is absorbed by the new medium.
Which refers to the change and wavelength that occurs when an object moves forward or away from the source?
Doppler effect refers to the change in wavelength and frequency that occurs when an object moves towards or away from a source of waves.
Occurs when the plasma membrane surrounds a large substance inside the cell and moves it outside the cell?
exocytosis
Where and when does diffusion occur?
Diffusion occurs when there is a concentration gradient i.e. a substance moves from higher to lower concentration.
What occurs when the plasma membrane surround large substance inside the cell and moves it outside the cell?
exocytosis
Which refers to the change in wavelength tht occurs when an object moves toward or away from a source?
Doppler effect refers to the change in wavelength that occurs when an object moves toward or away from a source.
How heat move'?
Thermal energy that can move from one substance to another is called heat. Heat always moves from a warmer substance to a cooler one. An increase in temperature means that heat moves into a substance.
What is the name for a change in the direction of a wave when it pases from one medium into another?
The change in the direction of a wave when it moves from one medium to another is called refraction. This occurs because the wave changes speed as it enters a new medium with a different density, causing it to bend.
