True
False
The relationship between wavelength and frequency is inverse
True
False
What makes sound waves different from light waves? Check all that apply.
Sound wave and light waves both require a medium
Sound waves are surface waves and light waves are transverse waves.
Sound waves are not visible, but light waves are.
Sound waves travel at a slow speed and light waves are very fast-moving waves.

Physical property
Density
What does magnetism mean?
Being made of metal
substances that are made of two or more different elements present in a fixed ratio
is the ability of a material to be attracted or repelled
