Calculate wave speed find the speed of a wave with a wavelength of 0.2 m and a frequency of 1.5 hz.

Speed(m/s)=frequency(Hz)*wavelength(m)
=1.5Hz*0.2m
=0.3m/s

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
