In the Bohr model, what happens to an electron when it absorbs energy?

• It remains in the same orbit

• It moves to a lower energy level

• It moves to a higher energy level

• It disappears from the atom

Which type of radiation is known to be the most dangerous due to its high energy?

• Radio waves

• Microwaves

• UV rays

• Gamma rays

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

• As wavelength increases, frequency increases

• As wavelength increases, frequency decreases

• Wavelength and frequency are unrelated

• As wavelength decreases, frequency decreases

Which color of light has the highest frequency?

• Red

• Green

• Violet

• Blue

What is the unit of measurement for frequency?

• Meters

How does the energy of a wave relate to its frequency?

• Energy is only related to wavelength

• Frequency does not affect energy

• Higher frequency means higher energy

• Higher frequency means lower energy

Why are radio waves used for transmitting music?

• They have high energy and are safe

Which element emits more energy when it releases purple light compared to red light?

• An element that does not emit light

• An element that absorbs more energy

• An element that absorbs less energy

• An element that absorbs the same energy

What happens to the wavelength as the frequency of a wave decreases?

• Wavelength becomes zero

• Wavelength increases

• Wavelength decreases

• Wavelength remains constant
