Concave lens explained in an easy to understand way.
Concave lens
A lens with a center thinner than its edges. Concave lens. A concave lens is a type of lens that spreads out light rays, making objects appear smaller.
Convex lens explained in an easy to understand way.
Convex lens
A lens with a center thicker than its edges. Convex lens. A convex lens bends light rays inward to focus them at a point, making objects look larger.
Frequency explained in an easy to understand way.
Frequency
The number of cycles or vibrations per second, measured in hertz Hz, is frequency. Frequency is how often something happens over a specific period of time, like sound waves or light waves.
Opaque explained in an easy to understand way.
Opaque
A material that does not let any light pass through. Opaque. In simple terms, "opaque" means you cannot see through it because it blocks all light.
Pitch explained in an easy to understand way.
Pitch
How high or low a sound is, as determined by its frequency. Pitch. Pitch is how we perceive the highness or lowness of a sound based on its frequency.
Reflection explained in an easy to understand way.
Reflection
The bouncing of light, sound, or heat waves off a surface. Reflection. In simple terms, reflection is when waves hit a surface and bounce back.
Refraction explained in an easy to understand way.
Refraction
The bending of light when it passes from one substance into another. Refraction. Refraction is the change in direction of light as it moves between different materials, like air and water.
Sound volume explained in an easy to understand way.
Sound volume
The loudness or softness of sound. Sound volume. Sound volume is the measure of how loud or soft a sound is perceived by the human ear, influenced by the sound wave's amplitude.
Translucent explained in an easy to understand way.
Translucent
Allows some light to pass through but scatters it. Translucent. Translucent materials let some light through but scatter it so objects on the other side aren't clear.
Transparent explained in an easy to understand way.
Transparent
Allows light to pass through. Transparent. Something that is transparent lets light pass through so you can clearly see whats on the other side.
Vibration explained in an easy to understand way.
Vibration
The rapid back-and-forth movement of matter. Vibration. Vibration is when something moves quickly in small movements back and forth or up and down.
