Visible Light
What is the top part of a wave called?
(Crest) or what is crest?
What happens when light bounces off a shiny surface, like a mirror?
What is reflection? or Reflection
What vibrates to produce sound in a guitar?"
What is strings?
or Strings
Name one material that conducts electricity.
What type of energy transformation occurs when you turn on a lightbulb?
Electrical energy is transformed into radiant energy (light).
Name the colors of visible light.
What is (ROYGBV)? or ROYGBV
What happens to light when it passes through water and bends?
What is refraction? or Refraction
Is sound faster in water or air?
What is liquid? or Water
What is static electricity?
What is electricity produced by friction? or Electricity produced by friction that gets a charge.
What type of energy transformation happens when you use a toaster?
Electrical energy is transformed into thermal energy (heat).
What kind of wave is a light wave?
What is Transverse wave? or Transverse waves
Name a material that light cannot pass through.
What is opaque? or wood, metal, foil etc..
What kind of wave is a sound wave?
What is Longitudinal compression waves?
or Longitudinal Compression Waves
How can you generate(make) static electricity?
What is friction? or by rubbing materials together such as a balloon and wool sock.
What energy transformation takes place when you turn on a fan?
Electrical energy is transformed into mechanical energy (movement)
What tool splits light into colors?
What is a prism? or Prism
What is the term for materials that let some light pass through but scatter it so you can’t see clearly? (MUST INCLUDE AN EXAMPLE).
What is Translucent? or Translucent (frosted glass, stained windows, wax paper).
What makes a sound have a high pitch? (Think about jump rope experiment)
What are waves vibrating quickly? or vibrating fast
What is the difference between a conductor and an insulator, and give one example of each.
A conductor allows electricity to flow through it easily (e.g., metal). An insulator does not allow electricity to flow through it (e.g., rubber).
Describe the energy transformation that happens in a kettle.
Electrical energy is transformed into thermal energy (heat)
What happens to visible light when it passes through a prism, and why does it create a rainbow?
Visible light is refracted (bent) as it passes through the prism, and the different wavelengths of light bend at different angles. This separates the light into its individual colors, creating a rainbow.
What does it mean for a material to be transparent, and how does it affect the path of light? (MUST INCLUDE AN EXAMPLE).
A transparent material allows almost all light to pass through it without scattering, so objects on the other side can be seen clearly. The path of light continues straight through the material. (PLASTIC WRAP)
Through which medium does sound travel the fastest: air, water, or solid, and why?
Sound travels fastest through solids because the particles in a solid are packed closer together, allowing vibrations to transfer more quickly. or What is solid?
How can you create static electricity using everyday objects, and what happens when static electricity builds up?
You can create static electricity by rubbing two objects together, like a balloon and your hair. Static electricity builds up as an electric charge on the surface of an object, and it can cause objects to attract or repel each other.
Explain the energy transformations that occur when you use a hair dryer.
Electrical energy is transformed into mechanical energy (fan movement), thermal energy (heat), and radiant energy (sometimes light).
