What else can I help you with?
Can you describe what high and low frequency electromagnetic waves look like?
High frequency electromagnetic waves have shorter wavelengths and higher energy, appearing as shorter, more tightly packed waves. Low frequency electromagnetic waves have longer wavelengths and lower energy, appearing as longer, more spread out waves.
Why are some electromagnetic waves harmful to you but others are not?
Electromagnetic waves such as x-rays and gamma rays have high frequencies and energies that can damage cells and DNA, leading to health problems like cancer. On the other hand, waves like visible light and radio waves have lower energies that are generally not harmful to human health. The extent of harm depends on the wavelength and intensity of the electromagnetic waves.
What are electromagnetic waves with high energy called?
Gamma rays. Only extremely hot objects or particles moving at very high velocities can create high-energy radiation like X-rays and gamma-rays.
Can lead stop electromagnetic waves?
Lead is effective at blocking or attenuating electromagnetic waves, particularly in the form of X-rays and gamma rays. Its high density and atomic number make it an efficient shield against these types of radiation. However, lead may not be as effective for lower-energy electromagnetic waves like visible light or radio waves.
How do electromagnetic wave affect us?
Electromagnetic waves can affect us through different frequencies of radiation. Low-frequency waves like radio waves and microwaves generally do not cause harm, but high-frequency waves like ultraviolet, X-rays, and gamma rays can damage cells and tissues in our bodies, potentially leading to health issues like skin burns, DNA damage, and increased risk of cancer. It's important to limit exposure to high-frequency electromagnetic waves through protective measures and safety guidelines.

What is the reason for ultrasonic waves not being in the form of electromagnetic waves?
Ultrasonic waves are high frequency sonic waves. They're sound, which is mechanical energy. Electromagnetic waves are waves of electromagnetic energy, like radio waves or light. Mechanical energy is different from electromagnetic energy, hence the reason for ultrasonic waves not taking the form of electromagnetic waves.

Gamma rays. Only extremely hot objects or particles moving at very high velocities can create high-energy radiation like X-rays and gamma-rays.
What kind of waves are microwaves?
Electromagnetic waves, just like light, but with different frequency and wavelength.
Are radio waves tranverse?
Yes, like all electromagnetic waves.

Its high density and atomic number make it an efficient shield against these types of radiation.

What requires a medium?
Mechanical waves (like sound waves) and electromagnetic waves (like light waves) require a medium to propagate through. However, electromagnetic waves can also travel through a vacuum.
Which types of these waves is not a mechanical wave?
Examples of mechanical waves are waves in the ocean and sound waves from devices like mouths, trombones, and radios. Electromagnetic waves like sunshine and X-rays are not mechanical waves because matter is not doing the waving.
Are the sun waves mechanical waves or electromagnetic waves?
Electromagnetic waves
Sound is not part of the electromagnetic spectrum because?
because sound waves are not a electromagnetic waves because they need a medium for travel....hence electromagnetic spectrum is based on the electromagnetic waves ..like radio waves , micro waves , etc....
