WebThe right choice is D Red Because the wavelength of the red color has the maximum value. Hence its speed has a maximum value in any medium.In which medium does sound … WebBlue light travels slightly slower in glass than red light, so it bends a sharper angle when it enters the glass from air. In physics, we say the glass has a higher refractive index for blue light than red light. There is a formula (Snell's Law) that you can use to calculate angles from refractive index, or the other way around. Answer 2:

why does the red light is the fastest - BYJU

WebIs blue light not travelling faster then red light in space? No it isn't. Oddly enough, it isn't travelling faster than red light in a prism either.

WebFirst, a darker object will absorb more radiation than a lighter colored one, and will thus heat up faster under bright light. Second, a very hot object that radiates heat often has a characteristic color via black body radiation. The color of a flame or star, for instance, can be used to identify how hot the object is. Answer 3: Great question! Web25 feb. 2009 · In C. japonica, the absorption of 680 nm (red) light by the lowermost chloroplasts is <2% of the absorption by the uppermost chloroplasts on a unit chlorophyll basis. For blue light in spinach, the estimated absorption by the lowermost chloroplasts was <5% of that of the uppermost (Vogelmann and Evans 2002, Evans and Vogelmann 2003). cajetan neubauer
