Mirror surfaces reflect light by bouncing of incoming light waves at equal and opposite angles. Glass surfaces reflect light due to the difference in refractive index between the air and the glass material.
Raft spiders typically weigh between 1 to 3 grams. Their size can vary, but they generally have a body length of about 2 to 3 centimeters. These spiders are known for their strong and agile legs, which help them navigate on water surfaces.
Two examples of probes are spacecraft like Voyager or New Horizons, which are sent to explore outer planets and the edges of our solar system, and scientific instruments like thermometers or pH meters used to measure temperature or acidity levels in various substances.
Two examples of luminous light are the sun and a light bulb. The sun emits its own light through nuclear fusion, providing natural illumination to the Earth. A light bulb, on the other hand, generates light through the electrical energy passing through a filament or gas, creating artificial light for various applications.
A camera lens system, which uses a combination of lenses to focus light onto a sensor or film to capture an image. A microscope system, which includes lenses and mirrors to magnify an object for observation.

Two surfaces with high coefficients of friction are rubber on concrete and sandpaper on wood. These surfaces have rough textures that increase friction and resistance to sliding.
When two surfaces are rubbed together, friction occurs, which generates heat and wear on the surfaces. This can lead to the production of small particles, called abrasion, on the surfaces being rubbed. If the surfaces are rough or have irregularities, they can interlock, causing the friction to increase and potentially creating damage.

Rough surfaces causes 2 sliding objects to microscopically bind to each other, when one object's protrusions falls into the 2nd object's dips, friction occurs, the rougher the surface is, the more dips/protrusions there are, and the more force it takes to break them free.
Any surface which is a fractals has a fractional dimension. But the value of the dimension is less than 2.
Rubbing a balloon against your hair. Sliding a book across a table. Skating on ice. Walking on a rough surface. Options 1, 2, and 4 are examples of friction as they involve surfaces rubbing against each other, creating resistance. Skating on ice, however, involves very little friction due to the minimal contact between the skate blade and the ice surface.
Two things that are often considered rough are sandpaper, which is used for smoothing surfaces but has a gritty texture, and the bark of certain trees, like oak or pine, which can feel coarse and uneven. Both have practical uses but can be uncomfortable to touch due to their abrasive qualities.
The factors that affect the force of friction include the nature of the surfaces in contact, the roughness of the surfaces, the normal force pressing the surfaces together, and the presence of lubricants or contaminants between the surfaces. Additionally, the coefficient of friction, which is a measure of how rough or smooth the surfaces are in contact, also plays a significant role in determining the force of friction.
Friction between two objects is caused by the microscopic roughness of their surfaces interacting. When the surfaces come in contact and try to move past each other, these rough surfaces create resistance that we perceive as friction. The amount of friction depends on the force pressing the surfaces together and the materials involved.

Different surfaces can significantly impact the distance mealworms travel in 2 minutes due to variations in texture, friction, and stability. Smooth surfaces, like plastic or glass, may allow for easier movement, leading to longer distances traveled, while rough or uneven surfaces, such as sand or gravel, can hinder their mobility and reduce travel distance. Additionally, surfaces that provide better grip may affect their speed and direction, influencing overall movement. Thus, the choice of surface plays a crucial role in the locomotion of mealworms.
