Energy
The ability to do work or cause change.
What is Energy
travels is straight lines
what is light energy
Sound made from
vibration
light travel in
waves
light passing through clear window
Transparent
It never ends
What is energy
light that bouces off an object
What is reflection
needed to move sound waves
air molecules or particles
sound trvels in
waves
light passing through stained glass window
What is Translucent
Energy due to motion
What is Kinetic energy
Light that bends
What is refraction
Cause of a high pitch
faster vibrations with more energy
both waves can be 2 ways
short and long
light can't pass through
Opaque
Energy that is possible
Potential energy
2 ways light can pass through if items are
What are transparent and translcent
cause of low pitch
slower vabrations and lower energy
speed of travel is caused by the
material the wave passes through
Radio energy transfer
Electrical energy to sound energy
2 types of potential energy
What are Elastic and gravitational potential energy
What happens to light in a dark room to see a blue wall?
blue wave lengths bounce off wal and into your eyes
High volume is caused but what 2 factors?
More energy, more vibrations
How light and sound energy are not alike
sound needs air particles to move vibrations whereas light can travel on it's own
2 Types of energy used by a pole vaulter and both chnage into what energy?
Gravitaational and Elastic potential energy both changing into kinetic energy
