Description
| Question | Answer |
| Wavelength meaning? | The distance between adjacent crests measured in nanometers. |
| What is the lowest radiation that a object produces? | Radio |
| What is deadly for us that can melt us and cancer? | Gamma ray |
| What ray makes us get Cancer? | Ultraviolet |
| What is the longest wavelength colour? | Red |
| What was the shortest wavelength colour? | Violet with 400 nm |
| What is the primary colours to make any colour? | RGB (red, green, and blue) |
| What are the secondary colours? | CYAN, MAGENTA, YELLOW |
| What is the sclera? | The white part of the eye, protects the eyeball. |
| What is the cornea? | A clear window in front of the eye which covers the iris and the pupil. |
| What is the iris? | The coloured part of the eye which surrounds the pupil. The iris controls how much light can enter the eye by changing the size of the pupil. |
| What is the pupil? | A black dot in the centre of the eye, its a opening through which light can enter the eye. |
| What does Lens do in the lens? | It is behind the pupil and it acts like a camera lens by focusing light onto the retina at the back of the eye. |
| What is the light-sensitive inner lining at the back of the eye. It is the processing unit where it has rods and cones which can detect light and turn them to electrical impulses that flow to the brain. WHAT IS THIS PART OF THE EYE CALLED? | Retina |
| What is in animal's eyes that when you shine a light, their eyes look like they are going to light up? | Tapetum lucidum |
| What is in the inside of the eye which is fluid that makes the eyeball to be round? | Vitreous Humour |
| When it is bright outside, what would your eyeball do to lower the brightness? | The iris will constrict, and it will make the amount of light to enter smaller, which will reduces the light. |
| What does the retina have to detect light and colour? | the rods and cones |
| Which can detect light sensitivity? rods or cones | rods |
| Which can detect colour? rods or cones | cones |
| True or false Your eyes (cones and rods) might get overwhelm and they will become fatigued with your brain temporarily perceives the opposite colour. | true |
| What is the meaning of a blindspot? | An area where the optical nerve meets the eyeball, which means that there is no rods or cones to detect light and colour. ur brain fills in the blindspot with surrounding colours |
| What is colour blindness? | When someone is unable to distinguish certain colours due to the lack of or damaged cones. |
| true or false your eyes see everything right side up. | FALSE, ur eyes see everything upside down, but our brain flips the image right side up |
| What is Nearsightedness (myopia) | Someone who can see objects near to the eye, but not far from the eye. The focal point is in front of the retina. |
| how to correct nearsigtedness? | Use concave lenses |
| What is farsightedness (hyperopia)? | See objects far from the eye, but not near to the eye. the focal point is behind retina. |
| How to correct farsightedness (hyperopia) | Use convex lenses |
| What surgery is it called to fix and reshape the cornea to help focus light on the retina? | LASER EYE SURGERY |
| What are non-compound eyes? | Consists of a round cornea, an iris, a circular lens, vitreous body/cavity, and photoreceptor cells. It is also known as 'camera eyes'. |
| What are compound eyes? | Eyes that insects and crustaceans have compound eyes which is made out of many individual units or screens called ommatidium. they see many small images put together |
| what is optical device? | any device that uses light |
| What are microscope? | A optical device that is used for viewing super small objects. it was at least two lenses |
| What are telescopes? | A optical device for magnifying distant object. |
| What are the two kinds of telescopes? | Refracting and reflecting telescope |
| What was the first camera? | Camera obscura |
| What was camera obscura? | A dark room with a small hole or lens at one side through which an image is projected on the wall opposite the hole. |
| What was the Daguerreotype? 1839 | The film was slow to react to light. Subjects had to stand still for many minutes. |
| what is the Kodak camera 1888 | A big box camera that had fast film but subjects still had to stand still for minutes. |
| What is the Leica 1? 1925 | The first compact camera! The film is now used in cartridges or rolls. |
| What is the Fujj DSX? 1989 | The first digital camera dubbed DSLR for digital single lens reflex camera. It used electricity and chip rather than film to use to record images. |
| What is the Sharp JSH04? 2000 | The first digital camera which is small enough to fit in a phone. THE IPHONE WAS RELEASED 7 YEARS LATER IN 2027. |
| How does light enter? (eye vs camera) | Pupil, Aperture |
| What controls the amount of light? (eye vs camera) | Iris, Diaphragm |
| What interprets the image? \ (eye vs camera) | Retina, Film |
| How is the light focused? (eye vs camera) | lens and lens |
| What stops light from entering? (eye vs camera) | Eyelid, Shutter |
| Pixel meaning? | A small square in an image with an assigned colour. Many pixels combine to form larger images. Pixels are used for screens, where as the term ‘dots’ is used for round pigments on paper to form prints. |
| Resolution meaning? | The number of pixels/dots that comprise a photo or a screen. |
