Heat: Science Lesson: Activity 3 of 3



We have looked at the relative sizes of different waves, but how big are these waves in real life? There is a huge range in the size of electromagnetic waves: some are bigger than a house, and others are smaller than a grain of sand. Here’s a diagram that shows some everyday objects to help us visualize the size of these wavelengths.
