What does a prism do? A. It changes the wavelengths contained in a beam of light.
B. It combines wavelengths to make white light.
C. It removes specific wavelengths from a beam of light.
O D. It separates the wavelengths contained in a beam of light.

D

the angles wich light is coming into the medium are not the same for all wavelengths (colors, at least in the visible spectrum). same for outgoing light.

the same it true for any transparent barrier between two different materials, like air and water.

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
