7th Grade Q2 Science Review

Front

What is ultraviolet light?

Back

Ultraviolet light is a type of electromagnetic radiation that is invisible to the human eye and has a shorter wavelength than visible light.

Front

How does ultraviolet light differ from flashlight light?

Back

Ultraviolet light is invisible to the human eye, while flashlight light is visible.

Front

What is the fastest medium for light to travel through?

Back

Light travels fastest through air compared to other materials like plastic and water.

Front

What happens to the potential energy in a stretched rubber band when released?

Back

The potential energy stored in the stretched rubber band changes to kinetic energy when it is released.

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an example of demonstrating the Law of Conservation of Energy?

Back

Rubbing hands together creates friction, converting kinetic energy into thermal energy, demonstrating energy transformation.

Front

What is white light made up of?

Back

White light is made up of a spectrum of colors, which can be separated by their wavelengths.

Front

What property is used to divide colors in the spectrum of light?

Back

Wavelength is the property used to divide the various colors in the spectrum.

Front

What happens to energy when ice melts?

Back

When ice melts, thermal energy is absorbed, causing a change in state from solid to liquid.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.
