Description : The characteristic invalid for heat radiation is that it travels – (1) in a straight line (2) in all directions (3) with the speed of light (4) heating the medium through which it passes
Last Answer : (3) with the speed of light Explanation: Heat is a form of energy. An important property of heat is that it flows from a body at higher temperature to another body at lower temperature.
Description : The speed of light with the rise in the temperature of the medium : (1) Increases (2) Decreases (3) Remains unaltered (4) Drops suddenly
Last Answer : (3) Remains unaltered Explanation: The speed of light with the rise in the temperature of the medium remains unaltered because speed of light doesn't depend on temperature. It does depend, however ... in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics.

Description : Assertion (A) :Sunlight reaches us without dispersion in the form of white light and not as a component. Reason(R) : Dispersion takes place due to variation of refractive index for different wavelength but in vaccum the speed of ... of A. (c) A is true but R is false. (d) A is false but R is true.
Last Answer : (a) Both A and R are true and R is the correct explanation of A.
Description : When a beam of light enters one medium from another, which quantity will not change? ∙ a. Direction ∙ b. Speed ∙ c. Frequency ∙ d. Wavelength
Description : An index of refraction less than one for a medium would imply A. That the speed of light in the medium is the same as the speed of light in vacuum B. That the speed of light in the ... greater than the speed of light in vacuum C. Refraction is not possible D. Reflection is not possible
Last Answer : B. That the speed of light in the medium is greater than the speed of light in vacuum
Description : The speed of light in vacuum "C" divided by the Index of Refraction "N" gives the: w) frequency of the light x) speed of the light in the medium y) energy of the light z) wavelength of the light
Last Answer : ANSWER: X -- SPEED OF THE LIGHT IN THE MEDIUM
Description : The characteristic invalid for heat radiation is that it travels : (1) in a straight line (2) in all directions (3) with the speed of light (4) heating the medium through which it passes
Last Answer : with the speed of light

Description : 3. Find out, from Table, the medium having highest optical density. Also find the medium with lowest optical density. -Physics-10
Last Answer : Lowest optical density = Air Highest optical density = Diamond The optical density of a medium is directly related to its refractive index. A medium with the highest refractive index will have the ... index. Hence, air has the lowest optical density and diamond has the highest optical density.
