    What is the critical angle for diamond (n = 2.42) submerged in water (n = 1.33)?1. 33°2. 49°3. 24°4. 17°5. Does not exist
    The answer to this is A. Diamonds are known to be very rare gems. There are people who would love to stock up on their jewelry that comes with diamonds because they know that these will sell well in the long run. There are some diamonds that do get submerged in water. There are still some reports of potential treasures that the pirates may have lost at sea. Some divers try to retrieve those treasures but they are far too deep in the ocean floor to be reached. Some of them may not even exist. Some diamonds will be able to withstand being submerged in water and can still be as good as new depending on how long it would be left there.

  • What is the difference between Lite and Light?
    What is the difference between Lite and Light?
    There is no big difference between light and lite. Both words are used to describe materials that are not too heavy in terms of their composition. Light comes from the Greek word 'leukos' and in Latin, it is called 'lux'. Light simply means the illumination that an object produced. Light can be used as a noun; it can be used as a verb and also as an adjective. As a noun, it refers to the illumination that comes from an object. For example: Can you see the brightness of the light coming from the sun? As a verb, it means to set fire to something, for example: can you tell the boy to light the candles? As an adjective, you can simply say, the table is very light, which means the table has little weight. Lite, on the other hand, is from the French word 'lite,' which describes an object that is light in composition, or products with fewer calories and fat

  • What is the difference between Luminosity and Brightness?
    What is the difference between Luminosity and Brightness?
    Luminosity and Brightness are two terms that are talking about light. If you want to measure the amount of light being generated from a source of light, or you want to describe the effect of the light generated, you need to have the understanding of the two terms. Luminosity is not totally the same as Brightness. Luminosity is simply talking about the amount of light emitted from a source of light like sun or light bulb. For example, the amount of light emitted on a sunny day will be quite higher than the one emitted on a very cool day. Brightness, on the other hand, is talking about the effect of the light received by the illuminated area. We can as well say, the brightness of the light depends on the luminosity of the light emitted. When the light emitted is high, the brightness will also go up and vice versa. Also, the values of the light received (brightness) can be measured using lumens, while the unit of luminosity is candela per square meter.

  • What will happen when a light ray travelling in glass is incident on an air surface?
    What will happen when a light ray travelling in glass is incident on an air surface?
    The answer to this question is D which is all of A, B, and C. Take note that there are always differences depending on the surface wherein the light would hit. If it would hit a translucent object, only some of the light may be reflected as translucent objects allow some light to pass through. This means that only a few rays of light will be reflected. When the light hits an opaque object, that is the time when all of the light may be reflected. A is the one constant thing. The light will refract away from the normal. Take note that there will also be differences depending on the matter that will be hit. It will be different for solids, liquids, and gases.

  • What angle will the reflected ray make with the reflecting surface if the angle of incidence is 34?
    What angle will the reflected ray make with the reflecting surface if the angle of incidence is 34?
    The reflected ray will have an angle of 56 degrees, or answer C. This is because the angle of incident and the reflected ray’s angles will add to 90 degrees. The easiest way to find the angle of the reflected ray, it follows, is to subtract the angle of incidence from 90. Likewise, if this question had been asking you to find the ray of incidence with a reflected ray of 56 degrees, you could do the same thing to find the ray of incidence. There is not a lot of information available to those who are not incredibly good at math that can be easily understood about why the angle of incidence and the reflected angle come to 90 degrees total. However, for those in math, it would make sense.
