Wave Model of Light
What acronym is used to remember the colors of the visible light spectrum in order of decreasing wavelength?
What is ROY G BIV?
This law of light allows flat plane mirrors to form images that are the exact same size as the object, upright, and virtual.
What is the law of reflection?
Lenses work because light bends as it passes from one medium to another. What is the scientific term for this bending of light?
What is refraction?
This foundational scientific concept states that cells are the basic unit of life and that all cells come from pre-existing cells.
What is the cell theory?
Put these biological terms in order from simplest/smallest to most complex: Organs, Tissues, Cells, Organ Systems.
What are Cells → Tissues → Organs → Organ Systems?
This type of wave moves material back and forth in the same direction that the wave travel, and is also called a compression wave.
What is a longitudinal wave?
This fundamental law states that when light hits a reflective surface, the angle of reflection is always equal to this other angle.
What is the angle of incidence?
These two key structural parts of the human eye control how much light enters: one is the colored circular muscle, and the other is the dark opening at its center.
What are the Iris and the Pupil?
Which part of the cell is responsible for cell growth, reproduction and other life activities?
What is the nucleus?
This primary organ of the respiratory system handles the exchange of gases during breathing.
What are the lungs?
Measured in Hertz (Hz), this term describes the number of oscillations a wave makes in a given amount of time.
What is frequency?
This type of mirror curves outward, making objects look smaller and upright, and is commonly used for rear-view mirrors in cars.
What is a convex mirror?
This type of lens is thinner in the middle, causes light rays to diverge, and is used in contact lenses to correct nearsightedness (myopia).
What is a concave lens?
If a compound light microscope has a 10x ocular lens (eyepiece) and you switch to the 40x high-power objective lens, what is the total magnification power?
What is 400x? (10x × 40x)
This vital liquid tissue circulates throughout the body to transport oxygen, nutrients, and waste products to and from cells.
What is blood?
Calculate the frequency of a wave that completes 900 oscillations in 30 seconds.
What is 30 Hz? (900 ÷ 30 s)
This specific type of reflection occurs when light hits a smooth surface and reflects an intact image, as opposed to diffuse reflection.
What is specular reflection?
This type of lens is thicker in the middle, causes light rays to converge, and is used to correct farsightedness (hyperopia).
What is a convex lens?
To fix the resolving power on a microscope so that the image becomes sharp and clear, you must adjust these two parts of the device.
What are the coarse and fine adjustment knobs?
This system is responsible for taking in information about environmental changes, processing a signal, and coordinating a response.
What is the nervous system?
Name the specific types of electromagnetic radiation found at the absolute highest energy end and the absolute lowest energy end of the electromagnetic spectrum.
What are Gamma rays (highest energy) and Radio waves (lowest energy)?
If you place an object very close to a concave mirror—specifically between the mirror's surface and its focal point—describe the orientation (upright/inverted) and type (real/virtual) of the image formed.
What is an upright and virtual image?
When an image travels through the lens of the eye, it is projected onto the retina in this specific orientation before being sent via the optic nerve to the brain.
What is inverted (or upside down)?
What are three differences between plant and animal cell organelles?
What is...
- Plant cells have a cell wall, animal cells do not.
- Plant cells have chloroplasts to preform photosynthesis, animal cells do not.
- Plant cells have 1 large central vacuole, animal cells have multiple small vacuoles.
A patient goes to the hospital complaining of severe lower back pain and notices blood in their urine. Which body system might be failing?
What is the excretory system?
