Based on the experiment which of the following can be inferred about the effect that adding salt has on waters freezing point

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.

answer; (b) clear with a slight blue tint;
