[i]"For example, both light and sound have wave properties."[/i]

Of course! Lyra remembered her grandmother used to tell her stories about waves and sound. "Sound," she used to say, "is made of vibration. That means moving back and forth, dear. So the vibration causes the tiny parts that make up air to also move back and forth, rhythmically, like they're dancing, see. And this dance, we call it a [i]wave[/i]. This dance is what reaches your ears, dear." "Oh! But grandma, I heard somewhere that light is also a wave? So does it mean that if this wave reaches our eyes, that's light?"  

Her grandmother had laughed at that. "Oh no, dear. Light is something different. Light is a dance of two waves, electronics and magnetic. Light is also a beast that's very hard to explain. Why don't you run along now, your mother is looking for you."

He violin was playing something, still very quietly. A jaunty little rhythmm. Lyra blinked and tuned herself back to the present. The sound stopped.
 
Vera was saying something. Combo move? "Oh, yes! Yes, that'll be great once we can figure it out!" Different kinds of waves. How do elementals get into the figure? "Maybe we can make lights dance in the air? Err..."

She turned to the teacher. Lyra wanted to ask her about everything, but it was probably better to be patient, learn it all in time. She bowed her head. "Thank you, Ma'am."

To Vera, she said, "So... do you want to look around?"
