Anatomy of the Eye
This fluid fills the aqueous chamber and maintains pressure in the eye.
What is aqueous humour?
This device has contributed to the knowledge of cell function, bacteria, viruses, and properties of metals.
What is a microscope?
This acronym represents the order of the visible light spectrum.
What is R-O-Y-G-B-I-V?
The high parts of a wave.
What is a crest?
The coloured part of the eye.
What is the iris?
This device is a combination of two reflecting telescopes mounted side by side. The telescopes are shortened by placing glass blocks inside. These glass blocks, called prisms, serve as plane mirrors, reflecting light back and forth.
What is binoculars?
This scientist separated white light into the spectrum colours by letting it pass through a prism.
Who is Isaac Newton?
The distance from crest to crest or trough to trough.
What is a wavelength?
The hole in the middle of the eye that changes size when muscles constrict or dilate.
What is the pupil?
This device has an objective lens that forms a real image of the object. Then an eyepiece lens magnifies the image further. It uses more than one lens in the objective and in the eyepiece to improve the sharpness of the image.
What is a compound microscope?
The additive primary colours of light.
What is red, blue, and green?
The number of cycles by a vibrating object in a unit of time.
What is frequency?
Light sensitive tissue at the back of the eye.
In this device light from a distant object is collected and focused by a convex lens called the objective lens. A second lens, called the eyepiece lens, works as a magnifying glass to enlarge the image.
What is a refracting telescope?
Cells in the retina that detect the presence of light.
What are rods?
If something vibrates 20 times in 2 seconds, it's frequency is said to be this.
What is 10 Hertz?
Millions of nerve fibers that transmit impulses to the visual cortex.
What is the optic nerve?
This device uses a concave mirror to collect rays of light from a distant object. The mirror is called the primary or objective mirror. It forms a real image, which is then magnified by the eyepiece lens .
What is a reflecting telescope?
The condition in which a person's cone cells are unable to detect certain colours.
What is colour blindness?
Waves with this spread out more when traveling through a small opening.
What is long wavelengths?
