Electromagnetic Spectrum Flashcard

Front

Which side of the electromagnetic spectrum has lower energy?

Back

Radio waves

Answer explanation

Radio waves have the longest wavelength and lowest frequency in the electromagnetic spectrum, which corresponds to lower energy compared to gamma rays, X-rays, and ultraviolet light.

Front

What is the relationship between frequency and energy in the electromagnetic spectrum?

Back

Direct relationship

Answer explanation

In the electromagnetic spectrum, frequency and energy have a direct relationship. As frequency increases, energy also increases, following the formula E = hf, where E is energy, h is Planck's constant, and f is frequency.

Front

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

Back

Inverse relationship

Answer explanation

Wavelength and frequency have an inverse relationship in the electromagnetic spectrum. As wavelength increases, frequency decreases, and vice versa, which is described by the equation: speed = wavelength × frequency.

Front

Which color of visible light has the shortest wavelength?

Back

Violet

Answer explanation

Violet light has the shortest wavelength in the visible spectrum, ranging from about 380 to 450 nanometers. In contrast, red light has the longest wavelength, making violet the correct answer.

Front

Color of visible light with the longest wavelength for a rainbow mural.

Back

Red

Answer explanation

Red light has the longest wavelength in the visible spectrum, ranging from about 620 to 750 nanometers. In contrast, green, blue, and violet light have shorter wavelengths.

Front

Order of colors in the visible light spectrum from longest to shortest wavelength.

Back

ROYGBIV

Answer explanation

The visible light spectrum is ordered by wavelength from longest to shortest as Red, Orange, Yellow, Green, Blue, Indigo, and Violet, which is represented by the acronym ROYGBIV. Therefore, the correct answer is ROYGBIV.

Front

Which type of electromagnetic wave is used for broadcasting radio signals?

Back

Radio waves

Answer explanation

Radio waves are the type of electromagnetic waves specifically used for broadcasting radio signals. They have longer wavelengths compared to X-rays, gamma rays, and infrared waves, making them suitable for communication.

Front

Mia went to the beach and forgot to apply sunscreen. Which type of electromagnetic wave is primarily responsible for her sunburn?

Back

Ultraviolet rays

Answer explanation

Ultraviolet rays are the type of electromagnetic wave that can damage skin cells, leading to sunburn. Infrared waves, radio waves, and microwaves do not have the same harmful effects on the skin.

Front

Which type of electromagnetic wave has the highest energy?

Back

Gamma rays

Answer explanation

Gamma rays have the highest energy among electromagnetic waves due to their short wavelength and high frequency. This makes them more energetic than radio waves, microwaves, and infrared waves.

Front

Which has a higher frequency, orange light or violet light?

Back

Violet light

Answer explanation

Violet light has a higher frequency than orange light. In the visible spectrum, violet light is at the shorter wavelength end, which corresponds to higher frequency, while orange light is at the longer wavelength end.
