Lab4: PostLab Flashcard

Front

Which type of Visible EM Radiation carries the most energy?

Back

Blue Light carries the most energy among visible light, as it has a shorter wavelength compared to other colors like red, green, and yellow.

Front

What causes the lamp colors observed in Lab4?

Back

The lamp colors are a result of a combination of all emission lines in the spectra, which produce the visible colors.

Front

Which wave experiences the least interference in a wave diagram?

Back

Wave 3 experiences the least interference, indicating it has a more stable amplitude and frequency.

Front

What type of EM radiation is used for cell phone communication?

Back

Microwaves are used to carry information to and from cell phones due to their ability to transmit signals over long distances.

Front

What is perceived when the human eye sees a continuous spectrum of colors between 400-700nm?

Back

This range of colors is perceived as white light, which is a combination of all visible colors.

Front

Define electromagnetic radiation.

Back

Electromagnetic radiation is a form of energy that travels through space at the speed of light, encompassing a range of wavelengths including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

What is the relationship between wavelength and energy in electromagnetic radiation?

Back

The energy of electromagnetic radiation is inversely proportional to its wavelength; shorter wavelengths (like blue light) have higher energy, while longer wavelengths (like red light) have lower energy.

Front

Explain the concept of emission lines in a spectrum.

Back

Emission lines are specific wavelengths of light emitted by atoms or molecules when they transition from a higher energy state to a lower energy state, resulting in distinct colors in a spectrum.

Front

What is the significance of the visible spectrum?

Back

The visible spectrum is the range of electromagnetic radiation that can be detected by the human eye, typically from 400nm (violet) to 700nm (red), and is crucial for vision and color perception.

Front

How do microwaves differ from other types of EM radiation?

Back

Microwaves have longer wavelengths than infrared radiation but shorter wavelengths than radio waves, making them suitable for communication and cooking.
