As the wavelengths of light decrease, they increase in energy. X-rays have smaller wavelengths and therefore higher energy than ultraviolet waves. We usually talk about X-rays in terms of their energy rather than wavelength.This is partially because X-rays have very small wavelengths.It is also because X-ray light tends to act more like a particle than a wave.t doesn't hurt at all-you can't feel X-rays. Because your bones and teeth are dense and absorb more X-rays then your skin does, silhouettes of your bones or teeth are left on the X-ray film while your skin appears transparent.
Hindutva, or Hinduness, a term popularised by Vinayak Damodar Savarkar in 1923, is the predominant form of Hindu nationalism in India. The Bharatiya Janata Party (BJP) adopted it as its official ideology in 1989.
Interestingly the word Hindu came into existence because of mispronunciation of a Sanskrit word by the ancient Persians some 3000 to 4000 years ago. The word Hindu is not a Sanskrit word. It is not found in any of the thousands of native dialects and languages of India.Neither it is a religious word. It is a secular word whose origin is rooted in the language of the ancient Persians, who supposedly shared some common ancestry with the ancient Indians.nterestingly the word India has the same origin as the Hindus. Those who feel appalled at the idea of someone referring to all Indians as Hindus should read this. Just as the ancient Persians and probably Sumerians mispronounced the word Sindhu, the ancient Greeks used to mispronounce the river Sindhu as Indos.
