What is the frequency of 12.24 cm?

Answer Expert Verified The frequency of a 12.24 cm microwave oven is – 2.450 GHz.

How do you calculate the energy of a photon of electromagnetic radiation?

The energy associated with a single photon is given by E = h ν , where E is the energy (SI units of J), h is Planck’s constant (h = 6.626 x 10–34 J s), and ν is the frequency of the radiation (SI units of s–1 or Hertz, Hz) (see figure below).

What is the energy of one photon of microwave radiation?

One photon of the electromagnetic wave energy from the 2.45-GHz microwaves is 1.623 × 10−24 J {E = hv = (6.626 × 10−34 J s) × (2.45 × 109 s−1)}.

What is the energy of a microwave?

Electromagnetic spectrum
Name Wavelength Photon energy (eV)
Visible light 390 nm – 750 nm 3.2 eV – 1.7 eV
Infrared 750 nm – 1 mm 1.7 eV – 1.24 meV
Microwave 1 mm – 1 m 1.24 meV – 1.24 µeV

What is the wavelength of a photon of microwave radiation used in food processing in meters?

The microwaves used to heat food have a wavelength of 0.125 m.

What is the wavelength of microwave radiation?

Microwave radiation is commonly defined as that portion of the electromagnetic spectrum with wavelengths between 1 mm and 1 m (or the equivalent frequency range from 300 GHz to 300 MHz).

What wavelength do microwave ovens use?

12.2 centimetres

What is the main advantage of a microwave?

You can directly control cooking time, thus you have much better control over how much power you use. They also don’t retain heat nor do they heat up everything in your kitchen. Microwave ovens use less energy than all conventional ovens or stoves since they directly heat up the water in the food….

What are disadvantages of microwaves?

Disadvantages of Microwaves

  • Cost of equipment or installation cost is high.
  • They are hefty and occupy more space.
  • Electromagnetic interference may occur.
  • Variations in dielectric properties with temperatures may occur.
  • Inherent inefficiency of electric power.

What are the positive effects of microwaves radiation?

[49] found that microwave radiation enhanced brain wave energy, decreased brain wave frequency, and increased the amplitude and power of delta frequency bands, indicating a decrease in learning ability [53]….

What are the advantages and disadvantages of microwaves?

There are certain advantages and disadvantages of microwave cooking. Microwaves are convenient to use, they do not burn food, they are highly economical and they heat food faster and healthier than other methods. On the flip side, you’ll need to use microwave-safe vessels for cooking….

Is microwave not good for health?

Microwaves are a safe, effective, and highly convenient cooking method. There is no evidence that they cause harm — and some evidence that they are even better than other cooking methods at preserving nutrients and preventing the formation of harmful compounds….

What are examples of disadvantages?

The definition of a disadvantage is an unfavorable situation or something that puts someone in an unfavorable situation. An example of a disadvantage is a baseball player not being able to play. An example of a disadvantage is a baseball team’s star player having to sit out because of an injury.

What problems can artificial intelligence solve?

Here are five global problems that machine learning could help us solve.

  • Healthcare. One of the biggest benefits of AI is its ability to trawl through massive amounts of data in record time.
  • Making driving safer.
  • Transforming how we learn.
  • Help us be smarter about energy.
  • Helping wildlife.
  • Challenges.

Why AI is bad for the economy?

The disruptive effects of AI may also influence wages, income distribution and economic inequality. Rising demand for high-skilled workers capable of using AI could push their wages up, while many others may face a wage squeeze or unemployment.

What is the main advantage of AI?

The following are the primary advantages of AI: AI drives down the time taken to perform a task. It enables multi-tasking and eases the workload for existing resources. AI enables the execution of hitherto complex tasks without significant cost outlays.

Which situation is enabler for rise of AI?

Answer. Answer: Which situation is an enabler for the rise of Artificial Intelligence (A in recent years? availability of cloud-based, hosted machine learning platforms….

What is the impact of AI on society?

Artificial intelligence can dramatically improve the efficiencies of our workplaces and can augment the work humans can do. When AI takes over repetitive or dangerous tasks, it frees up the human workforce to do work they are better equipped for—tasks that involve creativity and empathy among others.

Will AI take over human?

While narrow AI can outperform humans in some tasks, there’s little to suggest that more general AI that can emulate humans’ ability to respond to many different tasks will be delivered and put humans at risk in the near future. But we can’t rule it out completely….

Why is AI gaining importance currently?

From managing global supply chains to optimising delivery routes, artificial intelligence is helping companies of all sizes and in all industries improve productivity and the bottom line at every stage of the business lifecycle from sourcing material to sales and accounting to customer service.

Why we need AI at this time?

AI technology is important because it enables human capabilities – understanding, reasoning, planning, communication and perception – to be undertaken by software increasingly effectively, efficiently and at low cost. Applications of AI-powered computer vision will be particularly significant in the transport sector.
