You are watching: Which of the following statements are true concerning the reflection of light?
A diverging lens always produces a virtual image of things placed in former of it.A diverging lens always produces one upright image of things placed in front of it.
A ray of light passes native air into a block of clear plastic. Just how does the angle of incidence in the air to compare to the edge of refraction in the plastic?
Suppose a ray of irradiate traveling in a material with an index of refraction na reaches an interface with a material having an table of contents of refraction nb. I beg your pardon of the adhering to statements must be true for total internal reflection come occur?na > nbThe angle of incidence need to be same to the an important angle.na = nbThe edge of incidence have to be higher than the crucial angle.The angle of incidence need to be less than the crucial angle.
Which that the following statements room true concerning the eye?The far suggest of the regular eye is infinity.Astigmatism describes a defect in i beg your pardon the surface of the cornea is not spherical. Instead, it is more sharply bent in one airplane than another.Farsightedness deserve to be corrected with a diverging lens.Nearsightedness can be corrected v a diverging lens.The hyperopic eye focuses rays from an object at infinity in prior of the retina; the myopic eye concentrates rays from things at infinity behind the retina.
The far suggest of the normal eye is infinity.Astigmatism refers to a defect in i beg your pardon the surface of the cornea is no spherical. Instead, that is more sharply curved in one aircraft than another.Nearsightedness deserve to be corrected v a diverging lens.
A beam of light crosses a boundary between two transparent materials. The tool the ray enters has a larger index of refraction. I beg your pardon of the adhering to statements space true?The frequency of the light remains constant as that transitions between materials.The wavelength of the irradiate remains continuous as that transitions between materials.The wavelength the the irradiate decreases together it enters right into the tool with the higher index the refraction.The rate of the irradiate remains continuous as that transitions in between materials.The rate of the light rises as that enters the medium with the better index that refraction.The frequency the the light decreases as it enters into the tool with the greater index of refraction.
The frequency of the irradiate remains constant as it transitions between materials.The wavelength the the light decreases as it enters right into the tool with the better index the refraction.
Which of the adhering to statements are true for an image formed by a airplane mirror when the object is inserted in prior of the mirror?The image developed by a plane mirror is constantly an upright image.The photo is constantly larger than the object.The image formed by a airplane mirror is always a online image.The image always appears to be located the exact same distance behind the mirror together the thing is situated in prior of the mirror.The image developed by a aircraft mirror is always an inverted image.The image created by a airplane mirror is constantly a actual image.
The image formed by a aircraft mirror is constantly an upright image.The image developed by a plane mirror is constantly a digital image.The image always appears come be situated the very same distance behind the mirror together the object is situated in former of the mirror.
Which of the adhering to statements are true concerning the enjoy of light?For diffuse reflection, the edge of incidence is better than the edge of reflection.The reflection of irradiate from a rough surface is called diffuse reflection.The have fun of light from a smooth surface is called specular reflection.The edge of incidence is same to the angle of enjoy only once a ray of light strikes a plane mirror.For specular reflection, the edge of incidence is much less than the edge of reflection.
The enjoy of irradiate from a rough surface is referred to as diffuse reflection.The enjoy of light from a smooth surface is referred to as specular reflection.
Which of the adhering to statements space true for images created by spherical mirrors?A concave mirror constantly produces one inverted image on an item placed in prior of it.A convex mirror always produces picture that is the very same size together the object.A concave mirror always produces an image that is the same size as the object.A concave mirror constantly produces a real image of things placed in front of it.A convex mirror always produces one upright image of an item placed in front of it.A convex mirror constantly produces a virtual image of things placed in prior of it.
A convex mirror constantly produces an upright picture of things placed in front of it.A convex mirror always produces a virtual picture of an object placed in former of it.
Which that the adhering to statements room true worrying compound microscopes?In a link microscope, the image created by the target lens is a genuine image.In a compound microscope, the last image is developed by the objective lens.In a compound microscope, the final image is a virtual image.The focal size of the target in a microscopic lense is very huge compared to the focal length of the eyepiece.In a compound microscope, the image created by the target lens is smaller than the object.
In a link microscope, the image formed by the objective lens is a actual image.In a compound microscope, the last image is a online image.

When glasses (or contact lenses) are provided to exactly nearsightedness, where have to the corrective lens kind an picture of things located at infinity in order for the eye to type a clear picture of the object?
When glasses (or call lenses) are offered to exactly farsightedness, where need to the corrective lens type an picture of an object located in between the eye and the near allude in order because that the eye to kind a clear picture of the object?
To a swimmer under water, objects look at blurry. Once goggles are worn, however, the images are sharp. Why is this so?
The swimmer"s eye are adjusted to refraction that takes place as light passes native the air into the cornea. The goggles keep this.
