(a) 10 −12 m

(b) 10 −8 m

Identify the following electromagnetic radiation as per the wavelengths given below.

(a)  ${10}^{-3} \mathrm{m}$

(b) $1 \mathrm{nm}$

The wavelength,  $K_{\alpha }$ of X-rays produced by an X-ray tube is $0.76 \mathrm{\AA }$. The atomic number of the anode material of the tube is___________

The wavelength,  $K_{\alpha }$ of X-rays produced by an X-ray tube is 0.76 Å. The atomic number of the anode material of the tube is___________

In an X-ray tube, electrons accelerated through a potential difference of $15,000$ volts strike a copper target. The speed of the emitted X-rays inside the tube is $\mathrm{m}{ \mathrm{s}}^{-1}$

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R

Assertion A : EM waves used for optical communication have longer wavelengths than that of microwave, employed in Radar technology.

Reason R : Infrared EM waves are more energetic than microwaves, (used in Radar)

In the light of given statements, choose the correct answer from the options given below.

Match the list-I with list-II and choose the correct option.

Which of the following is the highest energy electromagnetic wave?

If the frequency of the electromagnetic wave is $3\times {10}^{17} \mathrm{Hz}$, then it corresponds to which part of electromagnetic spectrum

Radio waves are

What is the wavelength range of visible light ?

The principal of microwave is that if we can heat up the water molecules then they can transfer their heat to the neighbouring food molecules. As most of the food items have water molecules it is easy to cook them. The frequency of the radiation supplied should match with the frequency of rotation of water molecules which is about

The range of wavelength for Ultraviolet is from _____ to _____

What is Range of Radio Frequency Band of FM (Frequency Modulated Band)?

Give one application of radio wave.

What are the sources of ultraviolet radiation?

Write the wavelength range and name of the electromagnetic waves which are used in radio and television.

Write the wavelength range and name of the electromagnetic waves which are used in Earth satellites to observe the growth of the crops.

Write the wavelength range and name of the electromagnetic waves which are used in radar systems for aircraft navigation.
