Consider the effect of the following changes in Questions 14-18: 14.) (0.5pt) You increase the temperature of the filament. This will reduce the amount of (unwanted) radiation at 1100nm (T/F) 15.) (0.5pt) Increasing the temperature will increase the efficiency of the bulb (T/F) 16.) (0.5pt) You could improve the efficiency by increasing the surface area of the filament but keeping the temperature constant (T/F) 17.) (0.5pt) If you increase the temperature of the bulb, the light will look
