The Path of Light (5.8C)
Light is unique because it always travels in this specific direction until it hits an object.
What is a straight line?
This clear tool is used to refract light to make objects appear larger or clearer.
What is a lens?
You can see clearly through a window because the glass is ________.
What is transparent?
This is the form of energy stored inside a battery.
What is chemical energy?
This form of energy is produced by the flow of electrons through a complete circuit.
What is electrical energy?
A solar-powered calculator transforms this type of energy into electrical energy.
What is light energy?
This term describes light "bouncing" off a shiny surface, like a mirror or a calm lake.
What is reflection?
A lens that curves outward and brings light rays together to a point is called this.
What is a convex lens?
You cannot see through a wooden door because the wood is ________.
What is opaque?
In a flashlight, chemical energy changes to electrical energy, which then changes into this.
What is light energy?
In a circuit with a motor, electrical energy is transformed into this type of energy.
What is mechanical (or motion) energy?
True or False: Light can be reflected and refracted at the exact same time.
What is True (e.g., looking at a window and seeing your reflection while also seeing through it).
When light moves from air into water, it slows down and bends. This is called ________.
What is refraction?
A lens that is thinner in the middle and causes light rays to spread apart is called this.
What is a concave lens?
Waxed paper or a frosted shower door are examples of this type of material.
What is translucent?
When energy changes from one form to another, it is called an energy ________.
What is a transformation?
This is required for a circuit to function; it must be a "closed loop" or a ________ circuit.
What is a complete circuit?
This is the energy of "motion," such as a spinning fan blade.
What is mechanical energy?
This is what happens when a dark object takes in light energy and turns it into heat.
What is absorption?
To "magnify" an object means to do this to its appearance using a lens.
What is make it look larger?
This verb describes light passing completely through a transparent object.
What is transmit?
A hair dryer transforms electrical energy into these two types of energy.
What are thermal and mechanical (and sound) energy?
A buzzer in a circuit transforms electrical energy into this.
What is sound energy?
When you plug in a lamp, the bulb produces light energy and this "waste" energy that makes the bulb hot.
What is thermal energy?
A prism works because it causes light to do this as it enters and exits the glass.
What is refract (or bend)?
Scientists call the material that light travels through (like air, water, or glass) a ________.
What is a medium?
Shadows are created when this type of object blocks light rays.
What is an opaque object?
When you rub your hands together, you are changing mechanical energy into this.
What is thermal energy?
Sound energy is specifically produced when an object does this very quickly.
What is vibrate?
Name the transformation: A person eats a snack (chemical) and then goes for a run.
What is chemical to mechanical?
