Physics and Biology Quiz: Waves and Eye Anatomy

Number of vibrations per unit time, measured in Hertz (Hz).

Distance between two consecutive points of a wave, measured in meters (m).

Wave speed; how fast the wave travels from one point to another, measured in m/s.

Height of the wave from the midpoint to the crest or trough, indicating energy.

Formula relating velocity, frequency, and wavelength: Velocity = frequency × wavelength.

Waves where particle movement is parallel to wave propagation direction.

Waves where particle movement is perpendicular to wave motion.

Compression waves that travel through a medium, such as air or water.

Energy traveling as waves of electric and magnetic fields, includes visible light.

The range of wavelengths of light visible to the human eye, from violet to red.

Molecules made of long hydrocarbon chains for energy storage and insulation.

Nutrient essential for vision and maintaining healthy skin.

Test using iodine solution that turns black/blue/purple to indicate starch presence.

Process where plants convert sunlight, water, and carbon dioxide into glucose and oxygen.

Mineral necessary for the formation and maintenance of healthy bones and teeth.

A clear, dome-shaped surface that helps focus incoming light.

An opening in the center of the iris that controls light entry into the eye.

Contains photoreceptor cells that convert light into electrical signals for the brain.

Nearsightedness where far objects appear blurry; images focus in front of the retina.

Vision distortion caused by an irregular cornea shape.

Rigid structure in plant cells made of cellulose, providing shape and protection.

Jelly-like substance inside the cell where most chemical reactions occur.

Protective layer that controls what enters and exits the cell.

Cell's control center containing DNA; it directs cell functions.

Process where cells use oxygen to break down glucose for energy (ATP).

The beginning of the digestive system where food is mechanically broken down and mixed with saliva.

An organ that mixes food with hydrochloric acid to break down carbohydrates and proteins.

A long tube where digestion is completed and nutrients are absorbed through the intestinal walls.

Extracts water from digested food and compacts waste into feces for removal.

The movement of particles from a region of high density to a region of low density.

When light hits a surface, the angle of incidence equals the angle of reflection.

A camera that uses a small hole to project an image onto a surface.

The bending of light when it enters a new medium, changing its speed and direction.

A lens that is thickest in the center and bends light rays toward a focal point.

A lens that is thin in the center and spreads light rays outward from a focal point.

Glucose enters cells where it is broken down for energy.

The process in cytoplasm that splits glucose into two pyruvate molecules.

Product of glycolysis that moves to mitochondria if oxygen is present.

Cycle that breaks down pyruvate to produce energy and CO2.

Uses oxygen to produce water and ATP in mitochondria.
