15. DESTRUCTIVE INTERFERENCE IS CAUSED WHEN TWO WAVES ARE OUT OF PHASE. WHEREAS, CONSTRUCTIVE INTERFERENCE IS CAUSED WHEN WAVES ARE IN PHASE OR THERE IS NO PHASE DIFFERENCE.
FROM THE FIGURE, IT IS EVIDENT THAT IN FIG(A), THE WAVES ARE OUT OF PHASE AND HENCE CAUSE DESTRUCTIVE INTERFERENCE.
HOWEVER, FIG(B) REVEALS THAT THE TWO WAVES ARE IN PHASE AND THEREFORE CAUSE CONSTRUCTIVE INTERFERENCE.
16. LIGHT IS MADE OF THREE PRIMARY COLOURS, RED, BLUE AND GREEN AND THESE MIXED IN CERTAIN PROPORTIONS LEAD TO FORMATION OF SECONDARY COLOURS.
OBJECTS SELECTIVELY ABSORB AND TRANSMIT/REFLECT CERTAIN COLOUR FREQUENCIES. THE LIGHT WHICH IS REFLECTED/TRANSMITTED TO OUR EYES, CONTRIBUTES TO COLOUR APPEARANCE OF THAT OBJECT.
YELLOW COLOUR IS MADE OF RED AND GREEN COLOURS. HENCE FROM THE ABOVE WE CAN INFER THAT, BANANA APPEARS YELLOW BECAUSE BLUE LIGHT IS ABSORBED WHILE RED AND GREEN LIGHT IS REFLECTED. SO THE CORRECT OPTION IS (a).

The Ocrit angle is= 24.09 degrees
A beam of white light is incident on the surface of a diamond at an angle 02. (Figure 1) The index of refraction actually depends on the light's wavelength, so the different colors that comprise white light will spread out as they pass through the diamond (like in a prism). The index of refraction in diamond is nblue = 2.450 for blue light while the indices of refraction for the lower frequency colors are...

The electronic absorption spectrum UI (Cr(NH3)6]3+ (aq) is shown in Figure 11.5. One of the observed peaks is centered at about 303 nm. 1.a. What is the approximate value of the wavelength for the two other peaks? Which one of these three peaks falls in the visible region of the electromagnetic spectrum? The wavelength at this peak is (Amax), and this transition accounts for the color of the complex ion in solution. The energy of the transition occurring at...

3) Wave basics. (15 points) a) (10 points) Refer to Figure 1 below. The top curve shows the changing height/magnitude of a wave at a fixed point in space. In other words, it shows how the magnitude changes in time as the wave moves past the fixed point. The bottom curve shows the same wave, but shows it at a snapshot time, rather than a fixed point in space. What are the period, frequency, wavelength, and speed of the wave....
