When light from a bright incandescent light bulb strikes the cut-glass object, it also produces a colored stripe on the wall. that stripe isn't as smooth or complete as the stripe produced by sunlight. what is missing from the incandescent lamps stripe?
a. large portions of the visible spectrum are completely missing from the incandescent light. it consists of only of the individual primarily colors, rather than the complete spectrum available from sunlight.
b. its orange portion is too bright compared to its red, green, and blue portions because the incandescent lamp produces primarily orange light.
c. its green portion is much dimmer than that produced by sunlight because the incandescent lamp's filament is primarily red and blue in color.
d. its blue end is much dimmer than that produced by sunlight because the incandescent lamp's filament temperature is too low to produce much blue and violet light.

1. what is the relationship between wavelength and the penetrating power of an electromagnetic wave? a) the penetrating power has no relationship to the wavelength. b) the penetrating power increases as the wavelength increases. c) the penetrating power decreases as the wavelength increases. d) the penetrating power decreases as the wavelength decreases. 2. as ice melts and turns into water, the speed of sound through the material would most likely do what? justify your answer. a) the speed would not change because the material is always water. b) the speed of sound would increase because the density of water is less than that of ice. c) the speed of sound would increase because energy is added to ice in order to make it melt. d) the speed of sound would decrease because sound travels faster through solids than liquids. 3.which of these waves need a medium to travel through? a) sound b) x-rays c) infrared rays d) visible light
