Back

An apple appears red because it reflects red light and absorbs all other visible wavelengths.

Front

Where is visible light located in the Electromagnetic Spectrum?

Back

Visible light is located in the middle of the Electromagnetic Spectrum.

Front

What phenomenon causes a penny to appear closer when viewed through lemonade?

Back

The penny appears closer due to the refraction of light waves as they enter the lemonade.

Front

What type of electromagnetic radiation is responsible for the warmth felt from the sun?

Front

How does the color of an object relate to the light it reflects?

Back

The color of an object is determined by the specific wavelengths of light it reflects while absorbing others.

Front

What is the role of infrared waves in everyday life?

Back

Infrared waves are used in various applications, including heating, remote controls, and thermal imaging.

Front

What is the relationship between frequency and wavelength in electromagnetic waves?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.
