Electromagnetic Radiation Concepts

What is a characteristic of electromagnetic radiation?

• It can be seen, touched, and felt.

• It is odorless and tasteless.

• It requires water to travel.

• It only exists in specific locations.

How does the energy of an electromagnetic wave relate to its frequency and wavelength?

• Higher energy waves have longer wavelengths and lower frequencies.

• Higher energy waves have shorter wavelengths and higher frequencies.

• Energy is unrelated to wavelength or frequency.

• Higher energy waves have longer wavelengths and higher frequencies.

What determines the color an object appears to be?

• The object emits specific wavelengths of light.

• The object absorbs all wavelengths of light.

• The object reflects certain wavelengths of visible light and absorbs others.

• The object converts invisible light into visible light.

What is a spectral signature used for in scientific analysis?

• To measure the speed of light in different mediums.

• To identify an object's chemical composition and physical properties like temperature.

• To determine the distance of celestial bodies from Earth.

• To predict weather patterns on other planets.
