In my opinion, the answer should be option (A) instead of option (B). On the Richter scale (which is a non-linear scale), the power of an earthquake increases by 10 with every consequent number. Thus, an earthquake of 2 on the Richter scale is 10 times more powerful than an earthquake of 1 on the Richter scale. Thus, an earthquake of 8 on the Richter scale is more powerful than an earthquake of 6 on the Richter scale, by a factor of 10⁸⁻⁶, or 10². Thus, an earthquake of 8 on the Richter scale is 100 times more powerful than an earthquake of 6 on the Richter scale.

no it can not be option d as temperature has no effect on frequency. Wheather temperature increases or decreases frequency remains unchanged. So, the answer could be either time period or frequency.

Ashmi Narkar from The Shishukunj International School, Jhalaria Campus, Indore

Rakshit Mittal from Atomic energy central school 4, Mumbai
Class : Class 10
yeah, the answer is d

Ans 18:

Antarik Maity from Bharatiya Vidyabhaban, Kolkata
Class : Class 8
The correct answer should be D. Because temperature of air increases, density decreases and so, frequency of sound increases. But, according to me, it may or may not affect the wavelength, but the time period will definitely decrease. The options are a bit confusing.....

Got it as green color reflected thus will not be used for photosynthesis

Ans 5:

Siddharth Laxmisha from The Study Lecole Internationale, PUDUCHERRY
Class : Class 8
No, Answer D is not correct. They are talking about red, blue, and green lights not red, blue, and green pigments in a leaf. Red and blue lights are efficient in photosynthesizing and the green pigment is also efficient in photosynthesizing. Here, they are talking about lights, not pigments in a leaf.

Ans 6:

Ashwak from Cambridge, Jalandhar
Class : Class 9
Answer C is correct because Red and Blue light are absorbed and used for Photosynthesis . But in D it is written Green light is reflected ( correct ) but is used for Photosynthesis ( incorrect )
