How tall of a mirror should I get?
Mirrors should be approximately the same height, but can be six inches taller or shorter. The width of mirrors should be between 50- to 75-percent of the length of foyer tables.
Would a taller man be able to see his full height in the same mirror?
QUESTION Would a taller man be able to see his full height in the same mirror? (Select all that apply.) Yes, by standing far enough from the mirror. Yes, by shifting the position of the mirror vertically in the right way Yes, by standing close enough to the mirror.
What is the height of your image in a plane mirror?
A fourth and final characteristic of plane mirror images is that the dimensions of the image are the same as the dimensions of the object. If a 1.6-meter tall person stands in front of a mirror, he/she will see an image that is 1.6-meters tall.
What effect does your distance from the plane mirror that is half your height have?
The distance of the half-height mirror has no effect. If you move closer to the plane of the mirror, your image moves closer too. Try it and see! Object distance = image distance.
What size is a standard full length mirror?
Full-Length Mirror Sizes These mirrors are available in almost any size you could think of, with common dimensions anywhere from around 43 by 13 inches to 68 by 32 inches. Full-length mirrors could even be smaller or larger than those sizes.
Do you see more or less of yourself when you hold a small mirror farther away at arm’s length?
Note in your pocket mirror that the amount of your face you can see is twice the size of the mirror—whether you hold it close or at arm’s length.
Should you aim above or below a fish?
You always want to aim below the fish because the refraction of light makes the fish appear closer to the surface than they are. The distance that you aim depends on how far away you are from the fish, and how deep the fish is in the water.
What effect does your distance from a plane mirror have on the size of your image?
When the object is far from the mirror, the image is inverted and at the focal point. The image is real light rays actually focus at the image location). As the object moves towards the mirror the image location moves further away from the mirror and the image size grows (but the image is still inverted).
Why is the lettering on some vehicles backwards?
Answer. Answer: This is done so that the vehicle in front of it will be able to read it the correct way through the rearview mirror. So the “backward” lettering will be read properly when the driver looks through his rearview mirror.
Why is the lettering on the front of an ambulance backwards?
To make AMBULANCE easier read for vehicles in front of the ambulance. The most common modern usage of mirror writing can be found on the front of ambulances, where the word “AMBULANCE” is often written in very large mirrored text, so that drivers see the word the right way around in their rear-view mirror.
What are the properties of the image formed by a plane mirror?
An image formed by a plane mirror has the following characteristics:
- Virtual and erect.
- Behind the mirror.
- The size of the image is equal to the size of the object.
- Laterally inverted image (image of the left side visible on the right side).
Does a diamond under water sparkle more or less than in air Defend your answer?
So for diamond in air we get 24.6 degrees, for glass in air we get 41 degrees and diamond in water we get 32 degrees. The smaller angles allow more light rays to bounce around inside the crystal, so diamond in water is more sparkly than glass in air but less than diamond in air.
Why do diamonds disappear in water?
Because of its strong covalent C-C bonds, diamond has a relatively high refractive index. A water-clear mineral will only become “invisible” in water if its refractive index is identical (or very close) to that of water. Because of its strong covalent C-C bonds, diamond has a relatively high refractive index.
When a fish in a pond looks upward at an angle of 45?
A fish when looks up at an angle of 45° , the fish will look at the sky i.e. the sky will be visible due to refraction . The critical angle of water should be around 48.6° for water air boundary . Since the angle at which fish is looking is less than the critical angle the sky will be visible to the fish .
Why do diamonds sparkle refraction?
As the light moves through the diamond, it is scattered and fractured, creating the sparkle that diamonds are known for. This is the refraction. This refraction and dispersion also creates natural light and dark areas in the refracted light, depending on where the light hits along the planes of the diamond.
Do fake diamonds shine in the sun?
“A fake diamond will fog up for a short period of time whereas a real diamond will not because it won’t retain the heat,” Hirsch explained. 4. Hold it in the light to see how it sparkles.
Can a diamond be too sparkly?
Extremely well cut diamonds definitely don’t look fake or sparkle “too much”, but they do tend to look bigger than their ct weight and whiter for their color next to less ideal cut stones.
